Which reminds me - most rollers have a fork mount option so you can fix the bike in place. Oh yeah, if you want to use a trainer and keep track of effort through speed or distance, you have to have a rear wheel pickup computer.
If you're not interested in doing one-legged drills on rollers, why did you mention it? LOL
You can stay clipped in and let the other leg come along for the ride, as they do in spinning classes
However, somone posted a great article (I think by Chris Carmichael, but I am not positive) that talked about one leg drills and the ability to do a few other things with the trainer that you couldn't do with rollers
