I have a K2/ProFlex/Noleen carbon-crosslink fork and it's the best tracking fork I've ever ridden. It steers with precision like a rigid fork but gives you suspension. It's not that much heavier than medium travel telscoping forks but doesn't offer a whole lot of travel (only 3-1/2"). It's great for XC but I wouldn't pick it do any kind of riding that will require more than 80mm of travel.
