i think there is no "best" i think it depends on what you like and feel comfortable playing

Erik, you are wrong when you say that Yamahas are computer made. Doug Yeo plays on a Yamaha, and you can check out the Yamaha website to see video of how the trombones are made.

Yeah, those would be the custom lines. Of course they are hand made, or else folks like Yeo would never play on them. I am talking about beginner, intermediate, and advaced horns. Outside of the highest end pro horns.

Even the student models are hand made. All of Yamahas horns are hand made. Did you watch the videos on the site? The trombone, trumpet, and saxophone videos all say that all of the horns are hand made.

Merry Christmas

The videos will also show you that all of the horns are hand-made.
