hey again!

iv been playing cornet and trumpet for about 8 or 9years now and iv played on many mouthpieces, at the moment i play on a schilke 20# trumpet mouthpice and a 4W DW cornet MP, i love my schlkie i can usuaully get some nice high notes out of it, but i would like something a little shalower for when im playing high all the time, lead playing etc. i have been recomended the schlkie 14A4 but im not sure as iv never played one are the 20 and the 14 the same diamiter but with a shallower cup? any ideas? and can somone recomend me a new cornet MP, with a diamiter as big as the shilke? or maybe a good schulke cornet MP, has anyone had any experiances of shilke MP's?

cheers
