Yay!
I'm almost thinking about getting back onto rollers myself...
Just to re-state, if you do ride off rollers you won't go "zooming" anywhere. You have no forward momentum. It's more like tipping over from a FTU, except that you'll burn a hole in your carpet and/or put a flat spot in your tire.

Just like FTUs, getting hurt from falling off rollers is not impossible, but bruises to the ego are usually the worst you'll have.
