It seems like you aren't a very windy or brassy person, but how do you feel about learning trumpet/saxophone in concert pitch instead of the transposition mess?  For my purposes it works since I just need it for layering and botched solos, but I don't want to be a bad influence.
i have no idea. i don't particularly know anything about the trumpet or sax fingerings, but i have often assumed that in a parallel universe everyone could simply learn everything in concert pitch. also, professional players who play with groups of mostly guitar/keyboards, they seem to live their life in concert pitch with no questions asked. so i have often wondered about that and i don't know the answer but i suspect there is a good reason why the transposition keys exist. but i don't know quite know what that is
