Matching your float/weight/jig system is the key to catching more steelhead on jigs. The choice of various size floats,I use Thills unless it's likely that I'll loose the float,weight, generally hollow core lead cut to size, and different sized jig heads. My jigs vairy from 1/16- with split shot to 1/4+ with no shot. The combination depends on the depth, clarity, flow, structure, and weather conditions. For example, in extremely low water conditions I've used a clear Dennison float about the size of a small pencil--the jig alone will sink the float to the paint line. This system works only in moderate flow , and is difficult to cast. I think that it is imperative to load your float so that the slightest bump affects your float so you've got a chance at the light biters.
My brother and I fished a gin clear river in N. California where he could see fish stacked in a deep, long pool. I cast to them with conventional gear and didn't feel a thing, yet he could see fish move and mouth the baits. I put on a jig and floated it through them and got only a slight jiggle--which was enough to hook fish. Like so many fishing conditions the solution is situational. I enjoy this bb because it offers a chance to hear how others adapt to those challenges. Thanks for your insights & responses.
Snagley--do they require C & R for those wild backwater Singapore steelies?
