I have used Hemke reeds for the last 20 years. I discarded one the other day after only beginning to play with it, but I do not remember the last time I had to to that. The reeds do not typically warp. They are cut to center every time. The strength is consistent among boxes, and the tone is always great. They are my reed of choice for my C*(s), yanganasawa jazz, vandoren jazz, and otto link mouthpieces. I use them on alto, soprano, and tenor. I would love it if they could maintain strength longer, and I usually have to dispose of them within a few weeks after I begin playing on them, but non-synthetic reeds can't last forever.
