Rock Exotica vs Simmons

[Tim White]

Tim, what do you use? I know you have done some big stuff. Does Berta prefer to use the simmons ?

We have and use both. I use the Rock Exotica / PMI chest roller outside of caves; Bridge Day, Mexico pits, Whitesides, etc. No real reason other that it is a bit heaver. Berta still used a Simmons' ball bearing for timed rope climbs, but has started using the Rock Exotica / PMI for caving.
