I have played the d2 feel a couple of times this week. I can't find much wrong with them, on full shots or short-game shots. (I should probably mention that I have played them with irons & wedges only.) I have carpet-putted them all winter, and I never liked them much then, but this week on the actual greens I enjoyed putting them just fine.

The covers hold up nicely, and at $1 per ball it isn't the end of the world to lose one either!
