I’ve been testing both of these balls in the latest edition(I do this by hitting Driver and a FULL 9 iron from 125 yds out)and here is my personal data from 20 shots of each ball: the new ProV1 goes an average of 5-7 yards farther off the driver and an average of 4 yds off my full 9 iron with “ok” spin.. BUT, the new ProV1X flies significantly higher off the Driver, my full 9 iron goes approximately 122 yds with a higher trajectory and the spin on this golf ball is the best since I used a Titleist balata golf ball 25 years ago... I’d be very interested to hear “results” of other golfers..oh by the way, I must say that the Yellow colored golf balls spin more than the white!!
