paflyfisher;
It sounds like you are realy enjoying tying.
When I took my first lessons 2 years ago I made the choice of "Tyer's Grade" or #3's when buying capes. They are of nice quality and great for bigger fly's #12's and up and a few smaller one. I would suggest at least #2 grade or up. And, maybe just 1/2 capes.
Probably the most expensive tool, other than the vice will be the sissors. To make them last cut wire as far back from the tips as possible.
Good Luck and have fun!!
P.S. I don't see any of the PA people signed up for the FAOL Fish-In!!??
