Short story: Picked up the OLDS special tenor trombone a few weeks ago after a couple decades of not playing. Back THEN I played in college and even tied a year of Drum and Bugle (playing the baritone). Didn't have a mouthpiece so bougth one online...realized the OLDS has a pretty small shank and found a bach 12c that fit fairly well and BOOM I was playing stuff again while hleping my son in 5th grade learn his instrument.
Then I start researching and realize moutpieces can make a world of difference (would have been nice to know this in high school and/or college while I played

So...while I'm beginning (again) I am not really a beginner and played college level bands (yes Marching, but concert, jazz and quartets). Would love recommendations for a good sounding mouthpiece that will FIT my olds trombone (small shank...like the bach 12c, but no larger)
Humor me, you obviously smarter folks than me, and send me some recommendations? Thanks so much!
