Started using these plastic reeds about a year ago, and these were a standout; in my opinion much better tone and depth compared to the normal signature, and are very good to compared to cheaper wooden ones (Rico, D'addario, etc.). However, these do tend to run noticeably flat, and I switched back to my 3.5 V12s due to their even better tone and playability.
