I was given a box from friends for my birthday a few days ago, and played 9 holes with the D2 Straight, and 9 with a NXT (my regular ball). The distance was comparable and the "straight" factor - if you slice, the ball will slice. It may be slightly more forgiving than the NXT.
Feel for the D2 was quite good, comparable with the NXT, but the short game is where the D2 started to lack. I had a hard time getting the ball to check/slow down on short pitches and chips. Putting, the feel was great. As for rolling, i have no idea because they had just aerated the greens.
Overall, a good ball for the price but be cautions around the greens. I'm undecided if I'm going to continue to use them, or give them to my TopFlite loving friend.
