I've been on a small is better kick and am tying many of my nymphs down
to size 20. Problem is, I don't fish in the winter and don't have a
chance to test out these beauties. My theory has more to do with how
the fly sinks than trying to imitate the size of existing nymphs on a
given stream. Anyone have much experience with micronymphs? Should I go
back to tying no. 12 PT's?. Thanks, Frogge.

I tie a size 22 PT and use it successfully on brookies and land locked
salmon. There are any number of ways to get it down - let it be a
dropper from a weighted fly or use non-toxic shot. Regardless how you
get it down, it can be deadly. I don't think I have a PT bigger than
16. Most are 18 - 22. Small - 20 - GRHE also work well, as do other
small stuff.
