I've been trying to get my hands on a Lebayle Jazz chamber hard rubber tenor mouthpiece, but they're hard to find. Nothing on WWBW/eBay/etc. on the facing I want (around 7*). I could order one, but it'd take months. On the other hand, there's a fair number of LR and LRII chamber Lebayles out there, but I'm not sure how they compare to the Jazz chamber. I specifically want the Jazz chamber based on the recommendation of a local pro player I respect, but maybe the LRs are pretty similar? Does anyone have any thoughts on how the Jazz and LR(II) chamber types compare?
