Dave do you know anywhere that i could get a "Pebble"? I would love to MTA with a premie Classic Roc but noone seems to have any for sale. Mark i think had one but it was his and it would have taken a pretty penny to wrest it from him ...
If Mark can't get one, they probably don't exist here. You could try Discovering the World or Wright Life. They had them at some point. We do have MTA Roc, but they are the 180 size and weigh 113 gm.
