I have used them on both alto and tenor since January, in both marching band and wind ensemble. Signature is my favorite at the moment, but I really enjoy the different timbres I get using French, American and Studio prifiles.

For my purposes in Concert band the Signature 2.5 on a 5c mouthpiece fills the bill.
Like the tone produced and will stay with the Signature. For other purposes the Signature 2.25 on a OttoLink 6* gives me the tone I was looking for. Spent too much time looking for cane reeds that worked for me. Will be ordering French cut 2.5 for the OttoLink soon to see if that gives me a better result.

These reeds just "play" immediately! The signature is a great reed for me when i need to double on tenor from alto. I can just pick it up. and it plays as well as my best cane reed on the same set up, without the 'warm up' time.

I just finished a 3 hour continuous gig and the reed reacts as well at the end as at the beginning

It’s great. I actually use these on my bass clarinet. They are easy to play on and have great resonance.
