I've rode k2 for the last 10 years and really like there products. They have good tech for the value and I have never had one of there boards just shit out on me. I didn't do much research back in the day, just picked up a board at the end of the season for $175 and I liked it so much I've been riding them ever sense. Sure there a big corporation like Burton that stamps some boards out in china but there generally cheaper for the same tech that a similar Burton board would have. I have a 10/11 fastplant now and it has a 5 year warranty (complete core breakage; i.e. snapped in half) but only a 1 year on everything else. Its pretty forgiving to, you almost have to try and catch an edge.
I hit a jump weird in the trees this year at Arapahoe Basin and it flung me straight towards a tree! Well I bailed out (flopped around) in mid air and the board took the whole force of the nose on the tree (saving me). After it happened I just sat there thanking god to be safe and scared to look down at my bored because I knew it would be cracked or fucked up in some way. Well to my surprise it didn't have one scratch or crack on it! (maybe 1 1/2" micro scruff). Yeh I probably got lucky but meh, works for me.
Sorta off topic from k2 but along the lines of durability. I had another board that I'm not going to name the maker just incase I got a freak lemon, but I got a slight gouge on the bottom from rocks. When I went to ptex it, only one or two drops hit and the base started to split apart where the die cut met and I had to end up base welding it instead >.< Well that board was a msrp $500 board and so is the fastplant and I've never had issues like that with a k2.
Long story short I got a board with Bamboo, honeycombed aluminum core, carbon stringers, jib rocker, sintered base and hyper progressive sidecut for $275 new. Maybe with the exception of the heritage I just picked up and haven't rode the k2 is by far my favorite board for ALL-mountain. K2's aren't the best for any one area but they seem to do pretty well all over without having to go switch out boards. I also like there boots but there bindings are garbage imo.
P.s. If you have awesome team riders your going to pay for them and that money comes from somewhere (your pocket not theirs, which means higher markup)
Here's a video of the fastplant 10/11: http://youtu.be/3wm0NgC40l8
The 11/12's are noodles compared to the 10/11 though
