If the 14A4A worked, but doesn't now, there must be a reason. If it never worked, then why are you still using it?
I consider the 14A4A to be one of the most STUPID decisions a young player can make.
I havn't had problems with it. I was just thinking somthing else might be better. The reason I thought this is because I have heard Rowuk say that before, how it ia atupid for young players. When I got it I was completely ignorant ( and I still pretty much am) about mouthpieces. It was the easiest one to play in the store (out of the 3 or 4 others they had) so I got it.
