Vandoren Java Filed Red Alto 2.0

tried these reeds in no2 strength for my 1974 yamaha yas21 on a meyer g 5 mouthpiece. Ok, but i got a little warbling on anything below a low d, and the high palm key notes were a bit stiff to hit. that could be my technique but i really had to move around the reed to get the warble to stop coming through.
So in an effort to tame the palm keys i bought some Green unfiled java's in the same strength, no2's, and I really do get on with these. No warble in the low notes, and a smoother high d on the palm key. Much happier with these, the unfiled slightly softer greens really do compliment the meyer g 5 mouthpiece. Nothing wrong with the quality of the Reds.. just didn't work out for me.
