I was recently gifted a box of Vice Pro balls and put them in play during one of our annual 6-man scrambles. I am a long time Pro-V1x guy, with a brief stint With Callaway Chrome Soft (love the triple track 360), and honestly was super impressed with the Vice balls. I saw no noticeable differences in my game between the two. I think they'll have a spot in my bag for the foreseeable future
