I have had 2 Alphas. I liked them both. I like the A2 as well, especially for the price. Needs an update, though. Still, a better rod than the P.O.S. Sage FLi 8 wt that I cast last year.
I'm a fan of Scott, I just don't know how they have done well enough to keep its head above water when Powell, who built a BETTER performing rod, in my estimation, essentially disappeared. I have been underwhelmed by some of their rods. The 8 wt. E2 was a dog: too dead stiff. It may be a great rod in the 5 or 6 wt. Worth checking out. With everyone racing to make the most EXPENSIVE fly rod, if not the BEST one, Scott may be missing it's niche in the market. I don't know how you outdo Sage and Winston when they have more market share and a much greater variety of rods. I think they do well with the A2, the G2, which has a cult following, (I think it's a great rod but too expensive), a fair following for their salt water S2.5 (maybe) and their specialty 2 hand rods. They have had some real dogs, though. The S3 saltwater was here and gone in 2 or 3 years. The S3 rod was way too stiff. I don't know how they get the cash to do the heavy research the way Loomis, Sage and Orvis do. They all use some pretty cutting edge materials and new processes, so I understand. Field and Stream's quickie review of new fly rods gave the S4 a thumbs-up along with the Helios and the new St. Croix Elite.
Anymore, rods are barely differentiated from eachother. We are well into the realm of diminishing returns. Any rod from China or Korea will do as well as most Scotts will. 5-10 years ago, the American makers were spear-heading rod building technology. Now, they seem to be more boutique conversation pieces you can use to fish.
