I have enjoyed my 26 x 2.15" Almotions as tubeless tires. They did feel heavy and stiff to me when I was putting them on, but I feel like running them tubeless helped, and I've been happy with them, but if I found another tubeless tire with similar size and tread, I'd be willing to try it. If I were going back to tubes, I think I'd switch back to the Big Bens that the Almotions replaced.
