i knew what you meant derek. they're stronger and lighter, and they will slide over rocks better....no questions about that. i've personally seen one crack yes, there is a video on youtube where mark freeman cracked one by casing his MX bike.
whatever you do, don't defend that one guy....you know......my best bud over there. He's quite the "mouth" if you know what i mean, and he's been getting away with some low blows lately too.....just not a fan of him and if he comes over here trying to sling poo i'll be the first to do absolutely nothing about it, lol.
