I apologise for being obscure - its such a standard form of fishing here in BC, I guess I assumed it was done elsewhere, as well.
You hit it with lake fishing. We get some pretty unbelievable Chironomid (you might call them Midges?) hatches just after ice off, here in BC. The hatches continue through the ice free season (end of March - late December, here on Vancouver Island), but the trout target the hatching Chironies almost to the exclusion of all else in the springtime.
Heres a pretty good look at them
Size 16 - 08 chironimid on a long leader (depending on depth of water and the depth fish are intercepting the rising pupae), under an indicator - its bobber fishing, but it can be absolutely deadly, if you haven't tried it. I look forward to it every spring - I love the anticipation of waiting for the indicator to submerge.
Anyway - I thought a slightly longer, slightly faster rod than I am using now might help me out with some of those tricky long-leader hook ups.
