Im running an RX7U, the RX9U will be next bow. Seems like they perfected the 7 with the 9. I started with a V3 31, then went to V3X 33. The Mathews will out shoot my RX7. However you can be lazier with the Hoyt. The Mathews I found to be very unforgiving in comparison. Im a 30.5'' DL running 70-74#.
