I put a Vandoren Jazz 2 1/2 on my alto this morning and the sound was different from all the previous cane reeds I have played. However, it felt like it was harder to play and might be better in a 2. I couldn't find a 2 at the store. I was curious about the Javas, since I've never had any, so I bought a Green and a Red to see what's up. I haven't played either yet, but I will before I look back at your replies, if any. It's best if you have played them.
