The MK is the real deal... edge hold (check), grunting noises (yeah).
What surprised me is just how intuitive the board felt... I ride mostly Coilers, and felt right at home on the MK from run #1. (I usually need a few runs to get used to another maker's board...). I didn't *have* to ride it like a Madd, but when I did, it was more fun.
Mine was an impulse buy upon getting the Black Friday email from Donek... and I'm glad I was impulsive. It is a welcome addition to my mostly-Coiler quiver, and will get as much ride time as each of the Coilers. It definitely reminds me of the original Mad 158 I had for a couple of years, but also a little b it of my Nirvana Energy 174. When I **** up I know I'm not on a metal board, but when my technique is solid, it has every bit as much grip.
