Now you're not, but you're young and there are no guarantees they'll come back to your liking; and once they're altered, they're considered damaged goods on the trade boards. I really only chimed in on this because you said you were a student (and I assumed you were young) and I'd hate to see you make a mistake based on the hype of perfecting mouthpieces you see on this site from time to time. You say your rails are warped, but visbly so? If so, has the piece been melted or damaged? No shame in trying to repair a damaged piece, but I wouldn't be so quick to alter one that isn't visibly in need of repair. Heck, I know mouthpiece makers that swear by a bit of unevenness as giving their pieces that bit of character. If you perfect yours, you might find they'll never play the same for you. This reminds me of the stories told to me by one of my favorite techs. He'll paraphrase one of his clients who sent their favorite piece to be worked on and would complain to him about it, and in his thick English accent he'd mimic, "You ruined my mouthpiece!" You see, he never understood why someone would send their favorite mouthpiece off to get worked on when it wasn't damaged or otherwise in need of repair. This isn't an attack at all, but just something to think on. Heck, I get bent out of shape when folks send the Buescher mouthpieces off to be made into something they're not... but taking the chance on two vintage Selmer pieces... Man, I just hope it's not in response to the hype you find here, but seeing as you're willing to send them off with quickness being your main concern... well, I just hope it's enough of a problem for you that you would risk destroying what you love about these pieces in hopes of improving them.
