No problem man. You've got a life to live, can't spend all your time sitting in front of a computer screen. I'm hearing some pretty good stuff on the Kratons. The ESC apparently had issues when if first came out, but it sounds like they've resolved that. I think it can hold it's own, but I tend to believe the MT4-G3 is better built and technically tougher, but like you say, it'd be pretty hard to compare toughness with identical impacts/landings/etc.
