I listened to Rowuks thread reply in "fluid chops".
Adam Rapa's mouthpiece cups appear to be much smaller than my Bach 5C.
I am having problems now with my facial hair being forced back into my upper lip after only a few hours after shaving. It feels like needles and is quite painful.
Does anyone else find this so? Would a smaller diameter cup help? I am still building my chops and it is not to late to change if need be.
