Yeah, the 88 is really more of a comfort thing. The difference is not huge, but if you get a chance, try both and go with the one that feels more natural. I actually like the traditional beak (as a sax player) because it reminds me that I'm playing clarinet and helps to get myself into that clarinet state of mind!
Might I suggest the B45(dot) mouthpiece... It has a lot of the same characteristics of the B45, but dials down the bright focused sound a little. It's still free-blowing, but easier to get a full, round, dark sound. It's worth a shot if you like the B45.
