Howdy,
I now like the strike indicator method, since I've learned from my friend Bryan how to rig it correctly. The trick is to use a good floating line with the indicator snugged right on the nail knot connecting line and leader. The leader is kept short(approx. 4ft.) and a heavy beadeye or bullethead pattern is used. Roll casting is much more fluid set-up this way, although a standard backcast is quite awkward.
This method is unbeatable for Dog Salmon (I can't beleive people who think getting Chums to actually bite is'nt possible) and winter Steelhead. During low flow I think traditional set-ups with long leaders will be your best bet. Good Luck!
