Hook & Hackle has some very reasonably priced competition style nymph rod kits and blanks. See
http://store.hookhack.com/Limited-Cu...tinfo/XI1034K/ for example and some of the other blanks in that series.

I haven't used these rods / blanks so can't vouch for their performance. I opt'ed for an Echo Shadow II which I really like, but don't think its available except as a compelted rod.
