For many many years I have played synthetic reeds, for myself playing nearly everyday I want the constant sound. All the synthetic reeds do this the Ponzol is the best for myself. My advice don't try to use harder reeds than you normally use if anything come down a bit this gives you afaster response and flexibility. Don't worry about the toughness of the reed because it wont get weary on hard blowing, the next day there it is ready to start again you don't need to start looking through your reed boxfor another reed. What I do because I like a very big sound I put a small section of rubber on the back of the reed so the ligature clamps the reed very tightly. The Harry Hahn reeds have this feature so I use the rubber spacer off my old Hahn reeds.
