Pros: Excellent around the greens. Long off the tee. Great Feel.
All I can say is that this is an excellent ball. I typically play the Pro-V1 and this balls performance is right up there with it. It has great distance and feel off the tee. Callaway claims that they have engineered the aerodynamics of the SR1, 2, and 3 around the swing speed of the golfer which is easily measurable. The SR1 is made for swing speeds under 90 mph so it doesn't have to deal with drag at the lower speed off the club and focuses instead on increasing lift for greater distance. The SR3 is deigned more for swing speeds over 105 mph and the focus is more on reducing air drag do to its higher velocity. I have not tested the SR1 or 3, so I cannot say if I noticed a difference. It is a great theory however.
What I can say about this ball is how it performed for me. As mentioned, I found this ball to perform very well off the driver. I found it to perform even better with iron and short game shots. Approach shots grab and hold off the irons, and I even had a 9i back up a few feet. Even shot shots around the green from the rough have some bite. Last weekend, I hit a short pitch shot that took a hop and then stopped a few inches from the hole for a tap in par. This is where a ball's performance means the most to me.
I will definitely keep playing this ball and give it much consideration in the future when my stash of Pro-V1s starts to run low.
