I picked up another new Roc; this one is a yellow 12X KC Pro. Max weight with a puddle top. I threw it all day. I threw it on holes I shouldn't have thrown it. I couldn't stop throwing it. It came out of my hand like a bullet. It was fantastic, just a great, great Roc. It rode every line I put it on with a predictable fade at the end.
The store I bought it at had one more; it was light but the rest of the disc felt the same in the hand. I should have bought it.
I'm seriously debating the 4-hour round trip it would take me to get back to that store.
