I tested out a white cobra cross grove pad versus a white lc ccs pad with Menz 106FA. The cross groove pad was more "forgiving" than the lc ccs, i.e., initial plop down onto the paint didn't have the stiff "bounce" that the lc ccs has. My impression of course. Because of the beveled edge, it was nice to work with around concave and convex curves.
One thing I noticed, however, was the inconsistency of the grooves when comparing the orange vs. white vs. red pads; wide, thin and in-between, respectively. I did feel that when spreading the polish over the area you're going to work, it was easier to do so with the cobra X groove.
I would suggest that you purchase 1 of them in the cut you use most and give it a dance. EG., you need 3 new white lc ccs pads, make one of them a cobra X groove.
Heck, if Gary (wierd cuz it's my first name too) enjoyed using them on his Viper, you'd have nothing to lose trying them out yourself.
I decided to take a leap of faith today and picked up 7 LC CCS 7.5" curved pads to use on my new Flex 3401; 3 white, 3 green and 1 red. Gotta finish my Rustang and take care of 2 moderately swirled Porsches this month.
