I threw a beastly roller today with the Signal. 380', sloped fairway, hills, trees, 30' from the basket. If you have low arm speed, or are learning rollers, PLEASE do yourself a favor and pick one up. The Matrix is a winner, also PLEASE get one of these too. FR Vector flight, Axis feel. The Spin I really liked for putting. DEAD straight and holds literally any line you put it on (might have to work a little harder to keep it on a hyzer, but I digress) and super floaty. Personally, I don't like deeper putters for throwing, so I hated it off the tee, but if the Anode/Ion are comfortable throwing putters for you, definitely pick one up. It's a more US Anode.
All in all, another great batch of new releases for MVP. The Signal was underwhelming for a lot of people because it is quite understable, but even with a bigger arm, there are still uses for this disc. Kudos, MVP!
