No one can give you a reasonable suggestion on a mouthpiece without knowing what it is you want. You need to identify what the jumbo java isn't doing or is doing too much of, and how much of that you can't overcome yourself, before investing in a new mouthpiece just because someone else plays it. If there was a perfect setup for everything, we'd all play it. And there'd be no discussion and life would get pretty boring. (Every saxophone masterclass i've ever seen always goes to 'i play a _____ with a __ and a half ___ and a _____ligature on a _______horn...how else would a saxophonist start a masterclass if we knew the answers already?)
Identify what it is you want to change, get a concept of your sound in your head, then figure out what setup makes it easiest for you to get that sound. A dear friend of mine owns probably 15 mouthpieces, of all sorts of materials and designs, and no matter which one he puts on, he sounds the same because he has a sound in his head. he never identified what he wanted to change in his sound, he just hoped the different mouthpieces would magically give him what he doesn't know he's missing. That's how saxophonists get GAS...as the SOTW has deemed the syndrome.
hopefully that saves you from a lifetime of mouthpiece frustration. not trying to be harsh, just being honest. best of luck- mike
