Thanks for the replies.
Eric, I keep the hooks sharp. I check sharpness after release or getti g snagged.

Vinny, The hook sizes have varied from a size 10 salmonfly to a size 18 caddis nymph. Tippet was appropriate to the size fly. With the exception of usually staying with 4x tippet with nymphs.

I guess I will just have to keep trying.
