I'm currently trying to decide between playing the Pro V1 or Pro V1x. From what I understand the biggest differences between them is that the Pro V1x spins less with the longer irons and woods, but flies higher and generally straighter due to this less spin, while the Pro V1 has a softer feel and spins more with the longer clubs. Is this all correct and how big is the difference in distance between the two balls (driving distance in particular) and how big is the difference in spin between the balls? Thanks.
