Rollin'?

Last week Anne posted a video of a guy riding rollers on her blog. Today I found this post about rollers on Cranky Fitness. It's as if the rollers are summoning me from the attic. I've walked by them over and over again, but I've never actually tried to use them. They're Chris's rollers, but I could ride them if I wanted to.

It might improve my balance and my bike handling skills if I used them regularly. It would certainly be less boring than the trainer. But could I do it without injuring myself? After all, I did crash my bike on the trainer the first year I had it and I would have thought that was impossible.
