These reeds meet all my criteria, however they have one drawback in my opinion, and that is they are rather buzzy. In speaking with Rob, he believes this is an effect of the pronounced overtones of having made the reeds brighter. No doubt there is more tenor presence and the bass is a bit deeper than the older model, but it comes at the price of the buzziness. Other than that, the reeds are excellent. Air efficient and generally work very well, plug and play as expected.
