While I apprecaite this review, I am inclined to take it semi-seriously. I have played three fulls rounds witth the 20XI-X so far in three VERY seperate situations. The first time was in the rain, the second time on an overcast day with mist/wind and the third time, in beautiful sunny weather.
On all three occurances, I will say that my experience was entirely opposite to what the OP explained regarding spin and the ability to hold greens. Keep in mind, I played the X version of this ball which is supposed to be less "spinny" than the S version. For me, the X ball held greens VERY well. The main difference I found between this ball and say the ProV1 is that the Nike X ball didn't suck back on full short iron swings or full wedge shots. You say that you hit crisp wedge shots and while I believe you, I have the same ability and have been angered with beautiful shots with the ProV1 landing 8 feet from the hole and sucking back 15 feet. To compensate with this, I would choke down on a stronger lofted club (i.e. 9i vs. PW) and control the spin that way with the ProV1. When I played the ProV1X, it didn't suck back AS much but still required spin control on some shots.
With the 20XI-X, I could take a full swing with my 9i, PW, 56deg and the ball would hop hop, stop. Like literally stop on a dime. While I am a low handicap, I am no pro and certainly cannot consistently control spin with a ProV1. And I would say that many people on the this forum who claim to be able to really can't. So this ball reaction with the Nike ball was fantastic. I could get my distance, play a full swing and not worry about a surprise on TOO much spin if I hit a super clean shot. I also don't need worry about choking down on certain shots and try to get "cute" with controlling spin on a shot. On short chips and pitches, the ball would hop hop, stop and release ONLY slightly. This is perfect for people (like me) who like playing bump and run shots. Again, this is with the X version of the ball...I would be sure that the S version for me would spin more which is why I am surprised at the OP review on holding greens.
I agree with you on putting. The ball is very clicky on putts which is a personal thing with people. For me, I like the clickly feeling, others may not. On drives is where I think this ball really shines. The ball sounds like it explodes off of the driver and the flight is very penetrating. I gained some distance (which isn't important to me and shouldn't be for many really); I was more satisified at the tight ball flight; especially, on my second round with the ball in the wind.
So basically, what all of this really comes down to is the individual. I have heard rumors that this ball (similar to the Bridgestone B330) suits higher swing speeds. My driver swing speed is 116-119 and I hit my 6i 185. With MY swing, I could feel the ball compress and do the things I wanted. If others who play this ball do not have a consistent swing speed that is suited for this ball, then there is no doubt that they may not get all that they expect out of the ball. This is the thing will golf balls these days. Most people gravitate towards the high end balls when they can't even compress them! Bridgestone has proved this with their excellent ball fitting specifications.
I will continue to play the 20Xi-X ball. Will I be married to it, NO. I'm barely a Nike Golf fan besides their clothing which should show that my expereicne isn't biased. Will play the new Nike ball with others? Sure -->ProV1X, Penta, etc. But, to imply that it's not that good is a little unfair in my opinion and based on my experience, anyone that decides to play the ball should look at their own game to see if their "swing" matches this type of ball or any other high end ball for that matter.
