Rollers vs. Trainer is sorta like a "Which saddle fits my butt?" question. Everyone here has their opinion, but it really comes down to personal preference. I went from a trainer to rollers to a trainer to back to nothing and finally back to a trainer. Trainer time is boring! I figured rollers would keep me actively engaged. Then I realized that when I come home from work after dark and am exhausted , the last thing I want is to have to pay attention to avoid falling over. I just wanted to spin. Then I realized that dark isn't that dark anyway and got rid of the trainer. I finally broke down and bought another one this year because I realized how hard I've worked to get into shape and that dark really is dark in the winter and it's much easier to spin away in the house, regardless of how boring it is. Yeah, there have been a lot of realizations in the last year. The only constant has been that trainer time is boring as hell and I'd rather be on the road.
