You don't want your float going down the river faster than the current, but it can go slower than the current and catch fish but the optimum drift is a dead drift with the current. I feel you can fish a jig in nearly any water, sometimes it's a matter of positioning yourself correctly to get the optimum drift. As for jigs I run 1/8th & 1/16th in the summer and 1/4 in the winter, sometimes going to 3/8th but not very often. I like the Rainbow jigs because I can get them in any size(1/32-3/8) and the hooks will hold a steelhead without any problem.
