Show us your mouthpiece(s)!

I've been playing on this Schagerl Apredato Gileno Santana mouthpiece for the last 6 months and I absolutely love it. Prior to that I played on a much smaller Callet Solo mouthpiece for many years but after a lip injury due to swelling and scar tissue I needed to go to a larger diameter piece. I'm interested to hear from other players using Schagerl mouthpieces. 

I played a 1.5C through high school and college at the direction of my teacher.  Then switched to a GR67L when my trusty 1.5C "disappeared" during a concert and thought I'd try the newest coolest thing (they were expensive back then, but not the insane pricing they're at now).  I played that for a few a while, then recently had some endurance issues to work through.  I tried switching back to a 1.5C Megatone, and actually preferred it to the GR67L - I found it easier to play for me, but I was still struggling with making it through a long performance.

I had a Marcinkiewicz 3/5C sitting in my case that I had picked up on someone's recommendation years ago, and decided to give it another go.  I prefer the tone I get off the 1.5C still, but with the Marcinkiewicz I can get through my shows again so I've stayed on it.  An interesting comparison - the finish on the Marcinkiewicz looks like garbage after 20+ years, while the finish on the GR looks flawless after the same time and more use.  I might look for more SS pieces in the future.

Next problem....  I switched horns from a Yamaha 6345S to a Bach LT1901B in June.... and now I'm having intonation problems.  Now that I'm through the honeymoon period with that horn I'm finding that to play it in tune I need the tuning slide all the way in, and then I still need to lip it just a little.  I can lip it all the way up, but it's obvious I'm not in the harmonic slot of the horn.  Part of it is the Yamaha/Bach difference I know and I'm still learning the characteristics of this horn, but at a baseline I'm struggling to tune it.

Rather than get the horn modified or spend more money on yet another horn, I'm on the look for a new piece that might help.  I'm told maybe a shallower cup and/or tighter backbore might bring it up a little, though I'm hesitant to go shallower than the 3/5C since it's already affecting my tone.  Possibly I've just got a mismatch between hardware, or possibly I'm just a garbage player.  Unfortunately I don't live in an area I can just try out mouthpieces, so I'm dragging my feet making a decision on what to order.  With my flugel I notice that changing the mouthpiece significantly changes the tuning, so I have hope, though that difference is likely more to do with the couesnon taper than anything else.

On my flugel I play a Stork VF2-FL-C-1S (vacchiano #2 very deep, couesnon taper), and on my cornet I play a Curry 1.5DC (deep cup).  The cornet piece is an easy transition for me to double with and I don't perform on the cornet so it's not a huge deal other than being easy to transition.  The flugel stork piece is the only mouthpiece I've found that I can get my 1924 couesnon to play in tune (or as in tune as a 100 year old flugel can get anyway), though the tuning slide is all the way in even with it.  I also tried a Curry 600 80FLD on my flugel, and it plays so flat that I can't get it in tune.

I am an amateur player who is now in my 40s.  I have been playing a Bach 3C forever and could probably use an upgrade.  Any advice on how to get started on looking for a better mouthpiece?  I figure most people just try out a bunch of different mouthpieces but I don't want to buy a bunch of mouthpieces I won't use.  Thanks y'all!
