I've been using the Rico 73% packs (with the case) for about a while now. I love how the Rico case keeps the reeds from warping, but for quite a while I've been having problems with my reeds seeming extremely stuffy. I don't remember how my reeds behaved before I used this case, but I noticed that I grab a random reed that I haven't played in a long time that hasn't been stored in the Rico case (I play Vandorens and the reeds I'm not currently using go back into the plastic cases they're sold in), they play much better. The tables of the reeds are invariably quite warped, but even so they seem to play much better. I haven't actually stopped using the Rico case yet (Maybe too preoccupied with theory over practice?), but I wanted to know if anyone else has had a problem like this. A lot of people seem to love the Rico case, but is there any chance it's just not letting my reeds dry out enough? I might try the lowest humidity level (73 is the middle one, I think) to see how that goes. Thanks!
