Just my opinion, I didn't really get what I expected out of riding fixed MTB. I found that most of the enjoyment I got out of MTB was the coasting and "going fast" and on mountain bike gearing it's difficult to go "fast" fixed. I can say that riding by myself was fun, simply because it wasn't important for me to go fast. But riding with my fiance' on her geared hardtail had me struggling to keep up. Climbing is nothing, I actually like fixed for the technical sections, it's just the descents and high speed cornering that I missed. I would say go for it, but keep your mind open to single speeding.....way more fun, and honestly that's why I MTB...cuz it's fun.
