I gave up buying cane reeds well over 9 years ago, and have been using Hahn Reeds (I think they are either carbon fibre or fiberglass) I bought it from a shop in Stuttgart (der Gute tone, spelling prob not correcto) and have been using them ever since. One lasted me 6.5 years, they are bullet proof, one even cut my cheek when the mouthpiece slipped out and swung and drew blood, all without damage to the reed. I find them clear bright, easy starters straight out of the box, no need to soak or treat with kid gloves, seem to handle hard playing conditions weather wise. I do clean it irregularly, just to keep the gunge off, it's amazing that it plays so clean with lots of chips in the end of it.
In short I like em, not having to buy by the box and alway running down to the shop in search of another cause my reed just died is a hastle I don't need.
Yes they are expensive (last one's were $17 US) but it literaly lasts for years, without problems, Iv'e mentioned these to other guys, some have changed over others not. I'm certainly pleased I found them!
