rick,i have the #1 and #2 at home,the #1 is like a 10.5,and the #2 like a 7 but the 2 with a v cup and a anchor grip rim they are very comfortables
for me,i am a upstream player(the angle of the horn when i play is pointing up)and this kind of mouthpiece is perfect for that,they are similar to the warburton anchor grip.
