Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
i originally started out playing trombone, but that lasted for like a month lol. sax is just so much better. been wanting to try out soprano or tenor but just havent been able to get my hands on one, unfortunately. ;_;
for my reeds, I use Vandoren size 4's. I use a Rovner Versa ligature. as for the mouthpiece, I use a Yamaha 4C. I may get a metal mouthpiece in the future, we'll see.
Interesting, a better mouthpiece would certainly be a good investment for you. A good compromise would, imo, be a Selmer C star mouthpiece with Vandoren 3 reeds. Rovner ligature goes nicely! Though it all depends on the sound you want I guess
