Thanks guys. #24 is definitely on my list, and higher on the more than one night list. I have a few flies I've been wanting to try out my 8 wt on some smallies, so 17 is not out for me. I haven't spent any time fly fishing for those guys, but it is time to start.
I'll look into 18. I'll post more later. Gotta go! Unfortunately it is not fishing. <Big sigh>
