I recently bought an awesome [, remilled, soft, the whole nine. Quite beautiful, and if set heads on tails, it fits very tight and sturdy. However, if set head on heads, it wobbles quite a bit. Oh find this quite an inconvenience as my routine like to roll the coin, but it talks some. It isn't shimmed or Tefloned. Does anyone know a way to correct this?

I'm not sure that what your experiencing is not unusual, even using a non expanded [. I don't like to coin roll gaffs because I can't afford the inevitable failure, but if your so incline it's really just a matter of practice to minimize the feedback and use misdirection (patter) and background noise to make it work.

There are other set ups that might make it easier...
