Re: Advice about some 3 wt?
My favorite small stream 3 wt.; on an all-around basis, is Sage's ZXL. I fish a 7'6" 3 wt. consistently and have never been disappointed by its performance.
I think that Sage has discontinued this line in favor of what they now call the Circa.
You may be able to pick up a good deal on a ZXL at this point; either from a dealer with left-over stock or online.
I think it's worth a test cast, if you can get ahold of one.
