Put these three together on the putting surface the other day.
Although the Chrome Soft ball is significantly lower compression than the other two, I really couldn't tell a difference between the 3 in the feel department when doing a blind, random test. I experienced a slightly different sound from the Chrome Soft than the other two while using my Metal X Milled putter, but that has absolutely no effect on performance. I can't wait to get it into the simulator and see what happens on full swings (and then outdoors when the weather allows).
Interesting they had different sounds off the putter considering they all have the urethane cover. I guess I always kind of figured the cover had the most to do with the sound it would make off a putter, since you're certainly not hitting a ball with your putter hard enough to effect the core. I guess the core is just THAT much crazy different in the chrome soft, huh?
I'm so intrigued by these I wish I could order some right now.
