| I've only had the opportunity to play on a couple of Monette mouthpiece and the only Kanstul Mouthpiece that I have played is a Kanstul flugel setup that I own. That being said, right out of the gate, there are several reasons that I would choose the Kanstul "copy" (if it can really be called that) over the Monette.
The first reason for me is price. I have a hard enough time justifying to my wife that I want to purchase yet another trumpet accessory and if I presented her with the bill for what a Monette costs, she'd lose her mind!
Second, but probably more importantly, is consistency. Someone mentioned above that every Monette mouthpiece is different. Well, I got news for you. If something should happen to my mouthpiece, such as it getting lost or stolen, I don't want to spend that kind of money for a replacement that probably isn't going to feel or play the same.
Third, as many of you might already know, I have a real problem with the Monette pricing system. Chiefly, I think that they are waaaaay too high priced and I believe that better can be had for less. Case in point, Kanstul mouthpieces.
