I have a 1 1/2C and a 7E.....Both are comfortable to use once I became used to them. Like all things, it's what you're comfortable using and I found the Bach mouthpieces were quick to get used to and permitted me to play a greater range with ease, both high and low notes without straining or compromising my embouchure.
Highly recommend this range of mouthpieces to anyone playing a wide variety of genres.
