Yes, I have rollers. I ride them (usually on my Pinarello) occasionally but mostly use a CL bike I keep on a fluid trainer. Rollers are good for working cadence and balance and smoothness. Kinda of like boxers chasing chickens

I would suggest having a spotter and running between a doorway so you can grab yourself or they can grab you until you get the method down. Or you will bust your rear and maybe some other important parts.
