redrock
Probably. I don't have many SRRs in my collection the contents of which is mostly rough.
I am however a hiker and have spent considerable time beside large mountain pools, on the beach where the smooth river rocks pile up. You skip the SRRs.
There considerable pleasure to be derived from a well thrown rock as it skips across the pool, curving as the spinning rock slows.
Chunks just don't skip.
