I actually owned a Solo One. Yea, I don't know if I could hang w/ a 2:1 on Blackstar or MS, but I cleared every hill at Fullerton Loop w/ the 2:1. It's a real blast to challenge yourself that way and charge the hill as fast as you can. My legs definitely got stronger. Overall, I LOVE the Solo One, I think I'm going to buy another one. The soft tail really works, the components seem a little cheap, but decent and reliable it seems. The softtail does give a little flex, but its only an inch travel if that, so its nothing major.
