I got 4 clarinet Fiberreeds from Dannie and one from Windy.
2 Carbon Classic French M or 3 in strength. (one each from Dannie and Windy)
1 Natural Classic French M (or 3)
1 Copper Carbon Classic 2.5
1 Hemp French M (3)
The Copper Carbon Classic was way too soft. The Hemp reed was softer than the Carbon Classic, and perhaps darker in sound.
Taking the Carbon Classic and the Hemp models as a whole, I felt like the reeds are responding like a new reed, as if they are bending away from the rails of the mouthpiece. So although they play freely, there is an uncomfortable 'new reed' feel to them. I would characterize it as maybe a bit buzzy, and slow in response. This is felt primarily when I tried to play something with large interval jumps between registers. (And I am talking of playing the Bb or A clarinets here.)
I felt that this would probably work itself out rather quickly. But Windy told me (I think by phone) that Fiberreeds don't change like that. He said that they often develop a slight chip at the edge, but that this doesn't affect the tone. He said that when Fiberreeds fail and change in response, they do that rather immediately.
Windy, I will be testing to see if this is how it works for me. You play a Soft strength, and I play Medium. So I wonder if my M-strength Carbon Classic will warm up a bit and not have the new reed feel and sound, and I also wonder if my reeds will rather suddenly fail.
I think I will use my Carbon Classic M only for the G clarinet. If feels more open and easy-playing on the G. The G clarinet really deserves a bigger and wider mouthpiece. But since it still uses the same mouthpiece as the Bb and A, it is nice that the reed feels more open. It gives a beautiful rich sound on the G clarinet.
The hardest of the bunch was the Natural Classic M. That is the reed that is stark white in color. I will be able to play the Natural Classic on the A and G. Perhaps I will play it on the Bb also. I am pretty sure I would not want to play the M-strength Natural Classic in a band where I might need to play the first part on a Sousa March. But for when I play in church, it will probably work well enough.
I have ordered a Natural Classic M and Carbon Classic M for my soprano sax, and I will report back.
