My 13 year old son is moving along great playing the alto, p'mauria le bravo. Playing zzz reeds #3 on a carlton hard rubber mouthpice. It's a long and mcquade name brand. He likes it. I think it was $80. I think it's time to find him a better one. He has tried some name brand different mouthpieces in the $200, 250 range, but doesnt like them. Will they be that much better, with practice, or keep him playing the one he is on. He wants a metal mouthpiece for fun, any good, in-expensive recommendations. Thanks
