Nitto Mud Grapplers vs. KM2's

[Humdingah]

Can anyone who has had both comment on the two compared to one another? I'm looking at a set of 37s to go on a stock suspended H2 and wanted to see what everyone thought. I've got Mud Grapplers in 35" right now and they've worn great although they do shake at 80-ish on the freeway and they are by far the loudest tire I've had.

How does everyone who's tried the KM2's like them? Balancing issues? Wear? Any vibrations or shimmies at speed? Noise?

I like the Mud Grappler looks but would like something that doesn't sound as if I'm being constantly chased by a Cessena.
