Wow, I really appreciate everyones responses.. I think it will come down to cost mostly for me. However, a few of you have brought up a couple of good points.
One is weight. For the wheeling I am doing now, I can get away with a 3/16. However, I would like the MAX coverage- and it sounds like relentless is the one with the widest and most coverage. And I really like how his kind of protect the LCA bolts because yesterday, my buddy scraped both of his.
However, eventually if the funds present themselves, I would like to add on to the armor collection down there... This may sound like a dumb question but would the Relentless skid be "compatible" with future armor?
It does suck though.. because the rest of the day while I was driving I'm thinking, "ok I can do $300 bucks right now. I new I would get a better skid after destroying this one." So when I get back to my apartment my buddy Kevin and I are on the ground looking at it and I stand back up- and my iphone goes flying from my pocket and shatters on the ground. -awesome. So now I get glass shards in my hands and face whenever I use my phone, and I'll have to get a new one!
You didn't have to destroy your current iPhone to get a new one! Sorry to hear about that. You might try covering the screen with a single layer of clear packing tape to hold it together until you can replace it. Not sure how that'll affect the touch sensitivity, but it's pretty well frakked at this point anyway, right?
