Would reccomend you do a quick search of the archives....there is probably no less than 4 or 5 days worth of reading in the topic of mouthpices and what seems to work for what kind of horns.
as a personal plug I have two great mouthpieces for sale in the "For Sale" area

any input would be much appreciated
Any average sized mouthpiece would be a good start. I doubt you would like the mouthpiece I use and I would likely not enjoy playing the mouthpiece you choose.
