I'm not much of a trout fisher, but I do a lot of nymph style fishing for carp, bass and the like. I use a furled leader with either an orange or chartreuse butt section. Coat the indicator with payette paste and it floats. Pretty easy to get a natural drift and have a better chance to see the take.For a 9 or 10' rod I like an 84" furled with appropriate tippet. But, for crappies, a lot of times I'll use an indicator float or "thing-a-ma-bobber" and switch to a 48 or 60" furled leader. I'm pretty sure it would work for those really smart fish too Rg
