Ok, this is for you Schilke players and others who this would be similar: I'm looking at getting a Schilke 14A4A, and a Schilke 14. The reason for two is that I can play the A4A for lead stuff, and the 14 for concert band/orchestra. However, I've never in my life switched between two mouthpieces like this before. Is this a feasible idea? Or will I do more harm to my chops than good?
