No one answered yet...ok, scraping the bottom of the barrel, I will try and answer.
I tend to pretty much use only buzzers or spiders these days, although I do not fish a lot of fisheries.
My buzzers tend to be "realistic" patterns although I have a few"Okey Dokeys" if I think there are new fish in the water. I also have a few with UV backs for low light.
My buzzers are dressed from heavy through to "emerging" so I have something for fishing deep right the way through to fishing "in" the surface.
Added to the buzzers I have a few spiders that are dressed in black, brown, olive green and grey. They seem to work when the trout are nymphing just sub surface.
As the water cools, or early season, I may strip a cats whiskers or something black and "marabouey" on a sinking line.
