These are great reeds that I use with mouthpieces that have medium to small tip openings. They sound great and are very consistent. That said, you need to use a range of different reed types and strengths with different mouthpieces and instruments, the important thing is to get a good mouthpiece/reed combination which you find by trial and error. There is no 'one size fits all'. That said, most of the time I find I'm using either Java Red 3's or 2 1/2's or Vandoren Blue, 2 1/2's with most of my setups.
