I say go with the pro, I use that on the front. It's spacious between our coils and I want to make sure it smashes enough against them and I thought the first 2 might be too soft if the buffers were barely getting squeezed; just in case of the space.
Plus I like the black color since it blends into the background. I do great over bumps and crappy parts of the road, I think of your post everytime I go over a bad bump on the road and how my rogue absorbs the severe imperfections real nice. Use pro for the back too.
I don't know about a constant gauntlet of crap road, but I'm sure it makes everything less jarring. With all my mods, tires, etc, it worked for me. Good luck.
