Being in the States, I was just wondering what type of cornet mouthpieces are found on the solo bench of championship level bands in GB. I'm mostly interested in cup depth. If they are Wicks (or Wick type) - are most people using the "no letter" deep models or the shallower "B" cup models ? It seems that most of the folks over here are using "B" cups in the front row. Just wondering. Thanks for your help !!
