Here's my .02 on this....there is a time and place to fish jigs effectively,I carry several rods on my Cataraft.
So I'm ready when I encounter a stretch of water that screams for Hardware or a different set-up.
Some times I'll float a jig thru a hole just for a test,Then follow it up something else....whamm!!! fish on!
and sometimes it' works the other way too.
With the way conditions were last year low and clear,I had a killer year fishing just a Silent Approach Jig on a fixed float.
I'm not a big fan of Tipping my jig with bait,
I agree,why not just use a hook and yarn
But sometimes this can make the difference,

A lot of rivers I fish have bait restrictions,So you better have you're stuff together,
presentaion is the key and of course you need a Killer jig and you need to have several different designs and colors.
I've fished next to friends who were fishing a standard pink and white maribou Jig and catching fish (brats)
So I chose something completely different in design and color and can't keep the bruiser nates off

For those who want to get in to Jig and float fishing,all I can say is leave you're drift rod at home for a trip or 2 and give it an honest effort,you'll be surprised at the results.....Os
