I am currently trialing a Monette B1-2 mouthpiece which i really like the fat noise and whisper it has to it, however the rim is a bit sharper and has more bite than I am used to. I really like the depth the the piece, is the B1-1 a better option... is the depth and cup shape and volume the same? Anyhelp will be much appriciated. Btw just got my Eclipse Scratch Gold MR two weeks ago!!! man this thing can nearly play itself! Thanks to Leigh and John for such a speedy build and brilliant customer service.
