This is a continuation of the fish fighting conversation started under the 9141 Rod thread.
First off, rod talk. Until recently, for the most part, the design of DH rods has been heavily influenced by European requirements. Easy to understand since the largest market for these rods has in fact, been Europe. The main point of this in regards to the subject of fish fighting is that Atlantic salmon are larger than steelhead. A "trophy" sized steelhead of 20 pounds is no bigger than some "normal sized" Atlantic salmon in certain rivers. Some Atlantic salmon rivers offer the very real prospect of hooking salmon approaching or surpassing the 40 pound mark. It is only reasonable to expect that most DH rods are designed to have the capability for fighting fish 20 pounds or larger.
Secondly, the relationship of rod size by line designation between single handed rods and DH's is way off base. A #7 DH is at least one to two rod sizes OVER a singlehander designated as a 7, in most cases. A 590 grain Skagit line casts well on several makes of #7 DH rods, but it takes an 8/9 singlehander to accomplish the same Skagit casts with this particular line.
So, most steelheaders in the PNW would select a #9 singlehander for winter steelheading and a #7 singlehander for summer steelheading as being good "all around" rods for these situations. Most everyone would consider using a #11 singlehanded rod for fishing let's say the Grande Ronde or the Skykomish for summer fish as being total overkill. Yet, many of the same folks have no qualms about using a 15' 10 weight DH in either of those two circumstances. Remember the facts stated above - a #10 Dh is at LEAST comparable in power to a #11 single.
...and people wonder why they lose so many steelhead on a DH rod and have to fight a fish "off of the tip".
So, whattup with that?
#1. Big rods have the tendency to "suck" people into the fantasy of casting mega-huge distances. If that's your bag - casting "way out there" is the primary reason you fish, and catching fish is secondary - then that's cool for you, keep on a castin'.
#2. Big rods are easier - in the beginning - to actually go out and fish with because you can in fact just "bash" a cast out with such rods without having had to acquire very much skill. If you don't have the time available to practice, or the patience to spend the time to learn, or the discipline it takes to realize that at first you are not going to be able to cast very far, then get the biggest rod you can and bash away!
BUT, if you consider casting to be a means for catching fish, and you actually want to LEARN how to REALLY cast, and be able to use a rod that provides the most sport with the fish you are after, then be wary the big rod craze. When deciding on which DH rod to get, first consider what the MOST COMMON fishing distance is going to be. Then, factor in the MOST COMMON size and types of flies to be used. Finally, consider what the MOST COMMON size of fish is going to be. Determining these criterion should then allow you to be able to select a rod weight, length, and action that will be very well aligned with your fishing situation AND allow for having the most enjoyment while fighting fish.
Example
I want to fish the Grande Ronde effectively (under general conditions, barring extremely high and dirty, or winds over 25mph), and still enjoy "good sport" with its race of steelhead. This river is on the smaller side of medium as far as western rivers go. In most places a 70' cast (combined with wading) will put one beyond the centerline of the river. The fish are on the small side of the steelhead spectrum, averaging around 5 to 6 pounds (the 8 pounds touted by some individuals is pure *&#%$!). The flies are also on the smaller side, generally size 1 to 6, with weight coming in handy during the latter part of the season, as well as light sinktips.
Starting with rod length. 12 1/2' to 13 1/2' is plenty for covering out to around 70' and yet still allows for working in fairly tight to willow lined "highbanks".
Rod weight. Since everything about this fishing scenario is scaled towards the small end of steelheading, let's start at the small end of DH rods. A #5 would work - for the expert caster. What's more realistic are the #6's and #7's. Both weights will handle light sinktips and/or small weighted flies nicely, and can power through light to moderate breezes. Both line weights are also very well tuned into the fighting of fish in that 5 to 6 pound range, and have enough butt to handle 8, 9, and 10 pounders.
These parameters are as set for someone that is willing to truly learn to cast (with qualified instruction and consistent practice, attainable in 1 to 2 years). The rod range mentioned will easily handle the majority of casting situations on the Ronde, and yet they are not so overpowering as to make the catching of 5 and 6 pound steelhead seem like derricking panfish out of a pond with a canepole.
Now, let's get into how to fight a steelhead with a rod that actually bends...
Fish anatomy...
The first step to fighting fish effectively with a long rod is in understanding a bit about a fish's physiology. Fish are built for lateral muscle movement. Example - point your left index finger at the wall, like your hand is a gun, the index finger is the barrel of the gun. Curl your index finger back in halfway towards your palm and straighten it out again. If your index finger is a fish, it bends like this (sort of) to swim, only both ways (sides). Now, take your right index finger, press it against the tip of your straightened out left index finger and try to lift the left index finger up. If your left index finger is the fish, the backbone, much like your finger, has minimal flex in an up-down aspect. This means that if you are pulling in an upward direction when fighting a fish that you are in fact doing very little to "tire" the fish because you are "fighting" the rigidity of its skeletal structure instead of "fatigueing" its muscles. The quickest way to tire a fish is to apply lateral (sideways pressure) to work on its MUSCLES. This is ONE reason why a sideways attitude on a rod when fighting a fish is more EFFECTIVE.
Jarring or shocking of the fly is a most significant factor for causing hooks to dislodge from a hooked fish. This action causes slack to be introduced into the line, and BINGO! fish off! Next time you snag your fly onto a branch out of the water, "bounce" the rod, while holding it vertical, rapidly and vigorously, not up and down, but rather towards and away from the snag and watch how often the fly "pops" free. This is similar to what happens when a fish "headshakes" or "rolls around" on the end of your line. The way to combat this is by keeping the rod at a sideways attitude so that the majority of line is UNDER the surface of the water. The water tension on the line acts as a "shock absorber", and in combination with the "spring" of the rod, cushions the line from too much direct jarring, and prevents total slack from being introduced into the line. This is another reason why a sideways rod attitude when fighting a fish is more EFFECTIVE.
This does not mean that you should ALWAYS have the rod sideways... clearing obstructions you have to go vertical.
Rods that bend deeper into the blank when fighting fish (regardless of "action", if sized for the fish, any rod action can be bent into the butt) allow one to apply MORE pressure onto a fish WITHOUT the fear of breaking off or tearing out, which for most anglers will result in fish being landed quicker, provided one does indeed know the limits of their tackle.
