Well, to first start off, I have to say, both units are pretty buff. Installation on the prm swing arm skid was horrible. As a matter of fact, we're sending it back, but are getting another one because she likes it for the extra bit of clearance over the pro armor. The holes did not line up worth a dang, but that seems to be par for the course with this particular skid and company. For the pro armor swing skid, well this wasn't even a two person job and went on lickity split. The belly skid from pro armor also went on pretty easy, but is more of a two person gig if you wanna keep it easy. All in all, both good skids with good protection. It will mostly end up being what you want. The prm will give you a little more clearance right in between sprocket and disc, but still has the low spots because of them. I'll post pics as soon as we get hers back and installed. We'll do side by side pics with rulers next to them showing clearance and what not. Until then.
