Yep, not vintage. It's coming up on 2 years old. I'd stayed away from S3 because I'd heard that S3 was a throwaway tubeset. As in, use it for one season and throw it away. I'm thinking that may not be true but I won't know for a few more seasons. I wish TT had done more to market it. They might still be making tubes if they had. I feel like it's very competitive with other materials.
