yes. i have it and i have ridden it... For me (88kg) the board is perfect for almost all windsituations...on the lowend (10 knots) i rather use a bigger board...speed is awsome, riding on the nose is just like a tt, jumping on the "sweet" side is just perfect...good board. The board feels very light, turns very easy, has a sick amount of speed, a lot of control. You don't need to gybe it. It breaks out for a normal turn a little harder then with my other board, but it is ok.
In overpowered conditions it has a lot of grib and control. In very low conditions (10-12 knots, 17m2, 88kg) I couldn't keep height with this board, that was little better with my 148.
do a search on "mtx" on this forum, you will find a lot of handy info...
