Conclusion: I just finished up the three dozen yellow Z Star XV's I purchased in 2012, so I picked up another dozen this year on EBAY. Bit disappointed to find the softer, mellower yellow replaced with the brighter yellow that other companies are putting out, i.e. Titleist, Callaway, Pinnacle, etc.
Conclusion: Swing for swing, this ball plays nearly identical to Pro-V1x with extra stopping power and 'softness'. While not as soft as or spinning quite as much as the original ProV, it is high quality. The XV has a very distinct feel with full swings.
Summary: I have been playing the Pro V1x for a couple years and just decided to try out the XV the other day.( used to play the srixon ZUR-S when it first came out) I feel like this has to be the best ball on the market. You can hit the short irons low and the long irons high.
Summary: I have tested quite a few golf balls this year and have decided this ball is the best for my game. Great combination of distance and feel. Ball does not seem to spin out of control off of the tee. I also love the feel around the greens. Quite frankly, more golf ball than my game deserves.
Conclusion: I completely agree with your assesment that the Z Star spins a lot on full shots, but much less than ProV1x on half wedges and pitch shots. I found that very strange also. That being said, isn't you chart for "greenside spin" kind of backwards?
Conclusion: i loved this ball for everything but chipping. I could not get over how far this ball rolled out with brand new vokey wedges. It sucks because they are so durable and the yellow ball is impossible to lose, not to mention that it is very cool to see your ball flight in yellow.
Conclusion: this ball is amazing...it does everything i could possibly want. it has the distance, spin, feel, and durability i want in a ball, and usually then some. it has a super thin cover, which when you think about it, is better because all the technology is inside..
Conclusion: If Srixon had the marketing share that Titleist has this ball would probably be one of the top three balls purchased. It is long of the driver and does not have excess spin. I think the performance on full shots with this ball is matched by its performance on half swing shots.
