We test the mouthpiece with Woodstone 2 1/2 reed before shipment.I usually recommend Vandoren ZZ or Vandoren Java 2 1/2 as Woodstone is relatively hard to find.
Having said that, I have seen so many good results with so many other reeds and strength, so I recommend you to try various kinds of reeds to find the best set-up.

All manufacturers use different opening numbering systems. Please see our tip opening comparison chart to find your best tip opening.
