The new ProV1 had better feel than last years model with improved or equalled distance and spin and holding on the greens
The new ProV1x had the same feel as last years model with improved distance off the driver. The spin and hold on the green was similar to last years model.
I prefer the ProV1x off the tee for the extra distance and on the fairway but the ProV1 is better for the approach shots on to the green because of the better spin and hold on the green.
