I personally like Eugene Rousseau Classic pieces. I played on a 4R in high school on a YBS 61, and that was really good. I moved up to a 5R because the 4R was restricting for my playing style. Although I don't play on a Yamaha bari full time, I got a chance to play both a YBS 52 and 62 with my 5R. I generally don't like the feel of the 52, but it sounded good. I prefer the 62's sound and feel with my piece over the 52, but it is of course a professional horn (which actually doesn't matter for the sound, just the keywork). Hope this helps! -Lawrence
