several of my friends have them and really dig them. they do say that they can tend to be stiff when they first got the horn but after the "breaking in" process is complete, they're super happy with them. all new horns need to be broken in and also you can adjust the key height to your preference and the spring tension. i play a balanced action from 39 so the p mauriats feel very big to me...the bore is larger and the keys are offset so it feels foreign to me but they do play nice and have a good sound.
