So I received the balls just before Christmas.

Unfortunately I cannot play outside because there's over 1.5 meters of snow on the ground. I have been hitting them in my practice facility at home. The net return, Skytrak and quality mat.

Based on feel only, I find the Pro V1x hard and Pro V1 very nice. Spin numbers on my skytrak while hitting my 7 iron has a difference of about 300 rpm on a good strike. I find launch angle higher with V1x.
