Dave, just an observation, but you seem to come on here and start a lot of threads, and much of the time you'll ask a question, but rather than listen to advice from guys who would know, Rowuk and Solar Bell as two examples, it's almost like you want affirmation that the path you have chosen to take is the right one. At your stage of development as a comeback player, right now you need to eliminate variables so that you can figure out what's going on with your chops and technique. Find a middle of the road mouthpiece like a 3C, 5C or 7C, and STICK WITH IT. Otherwise you'll throw everything out of balance and progress will be hampered because you won't know if the issue is a chops issue, or an equipment issue. If you let yourself get used to a certain setup for an extended period of time, you won't be off balance due to jacking your equipment around - whatever issues need to be addressed will be you and your chops, assuming that you have a horn and mouthpiece of decent quality.
