I have no problem with different. Inferior or unsuited is a different matter. Life's short. Why spend time overcoming a problem when you can do so by picking up another horn. You never know when that pivotal moment comes along. Twenty or so years ago, I was playing a gig in a dingy little bar. The audience consisted of two men and a dog. One of the men turned out to be a one of the countries biggest booking agents at the time which lead to about a decade of well paid work. Imagine if I had of said to him "Look I'm not playing my best. I am trying to overcome/ discover some things about horn as it doesn't sit well with me." His response would have been " Well what are you playing it for?" I believe you should try to develop a relationship with a horn.( I can't believe the number of people on this site who have large numbers of trumpets. Don't know how they really get to know the nuaces of any of them) When people on this site say they have a compatibility problem with a mouthpiece, there is no end of advice about a replacement. Can't see how this is any different really. People on this site often personify their horns and talk about them like a partner. There is lots to get to know and discover about someone you really like. Don't care what the label says. I can't see the point of persisting with a fat ugly one if you can find one you truly love.
