Thank you for posting here, Daniel. It's always nice to see official representatives from major tennis organizations posting on this forum.
I just have to say thank you for creating quality products. I used to use the Pure Drive line, but stopped using it due to arm issues. I now use much softer, more arm friendly racquets.
But I love your strings. I think the Nv.Y is the absolute best syn gut on the market. It's a great string, and if I wasn't using poly, I'd be using the Nv. Y.
