Joe Valencic gifted me with a 6'6" 2 piece 2wt he built on a Forecast blank. The first fish I caught with that rod was my first brookie in a mountain stream in the Shenandoah Range in Virginia while fishing with my great friend (and brookie mentor & guide!) Tim Grubbs (FAOL's Grubb). I got it on a #14 Klinkhamer.
Joe also built a 4 piece Forecast 6'6" 2wt for himself & he said his is a good bit faster in action. I have uplined mine to a double taper 3wt line & it performs very well.
I can't speak of your other option, but the Forecast blank will not disappoint & it's been proven in those Virginia waters.
Whatever you decide, enjoy it & tight lines!
Mike
