I use an Eddie Lawton on my 10M. I got hold of a Brilhart, having heard great things about them, but have never settled with it, and after a back-to-back session with the Lawton, it's sitting on the shelf unused. However, I can't say I am 100% happy with the Lawton either and am still looking. I also have Runyon - to be honest, for me, it makes a raucous din and intonation on the lower notes is difficult to control. But we're all different and so are the saxes - it's just trial and error and what works for one won't neccessarily work for another.
