Pros: This ball is long- Stupid Long
Cons: Doesn't stop as well as the ProV1 on fast greens, Durability is below average for a premium ball
Last month I was lucky enough to receive a dozen of Nikes 2012 version of the 20XI with the purchase of some new clubs (I begged to have them thrown in), and just recently started playing them (I had to wait to finish my opened box of 2011 ProV1's, I am a bit OCD like that).
My first impression of the ball is that it is long. Right away, from my first swing, on the first hole of my home course, I gained ~15 yards at the tee, putting me in great scoring position on what can be a difficult and hairy par 5 if your drive comes up short. Thats a ton of distance to a guy like myself who averages only 265 off the tee (GPS measured) with a good, 85% power controlled swing. So to see ~280 yards showing on my Skycaddie with every good drive was nothing short of incredible. Im not one to believe marketing hype, but this time, the proof was there for me to see. Never before have I seen a ball give me these kind of results.
First off, this ball has plenty of spin, so dont shy away from it on that account. I will say that I find the ProV1 to stop a bit quicker on fast greens, but have no complaints at all with the 20XI. Of course this is all personal opinion, as I dont own a launch monitor to tell me how much backspin I put on the ball. But I know when I hit it well, and I know how the ProV1 behaves. There isnt a ton of difference, and in the case of very large greens, I actually prefer the 20XI, because its spin on the green gives me more options for where to put it. I know if my shot is good, I can overshoot the pin by 3 or 4 yards, and it will back up closer to the hole, barring steep slopes.
For me this is a non issue. If a ball makes it 18 holes, it becomes relegated to 'practice'. But I will say the 20XI was more beat up from wedge shots than similar offerings from titleist. While it is more Durable than the Taylor Made Pentas I played last year. I just finished my second sleeve of the 20XI, and they consistently last 18 holes, or ~80 strokes. I found the ProV1 to be in better shape, even after a bad 90+ round than the 20XI's were at 80 shots. If your a stickler for durability, this is not the ball for you. But if you dont expect more than a single round out of your balls, then the 20XI is a wonderful ball.
I am halfway through my box of Nike 20XI's, and I am extremely happy with the ball. I currently have a backlog of ProV1's (6 boxes), so it may be a while before I switch permanently, but this is definitely my ball of choice as of right now.
I would recommend these balls to any serious player, which is surprising to me, because I did not like ANY of Nikes previous offerings. If you lose a lot of balls, or are looking for a more economic choice, this isn't quite the one for you. But if you lose very few balls, and want premium performance, I would certainly put my stamp of approval on the 20XI. I found it to be wonderful in all areas that were important to me, and played some of my best golf with this ball. I had a difficult time getting yardages down, with a new ball as well as new Irons, but once I did I gained a lot of confidence when playing with this.
