Just got Davey's Wet Fly Video which I found very interesting. Excited to try out some of those techniques. Everyone seems to like the Invicta a lot so I set about tying some. Fairly experienced, but haven't done alot of wet fly tying besides basic wet hackles. Recipe calls for rolled hen pheasant center pheasant tail. I don't know what "rolled" means. I can guess, but wanted to make sure. Anyone ever subsitute a bit of CDC for the wing.

Not a tying question, but are any of the techniques davey showed effective when it gets cold (besides the intermediate line) or are the fish too deep and sluggish.

Thanks
