I've got a pretty stiff board as well. I knew it was going to be stiff, turns would be a little harder to initiate, and it's poor for jibbs, but it still took some getting used to. However, once I was comfortable with it, it totally matched my style of riding. I love this thing! It is so stable at high speeds with no chatter at all, it's amazing for launching off jumps and stomping jumps (even though it's a bitch to Ollie), and the edge to edge transfer is flawless. A little hint would be soft, loose, legs and a steady bend in the knees at all times. It doesn't take much to catch air out of nowhere while bombing through the chop (usually cuts right through, but because it won't often flex around them, sometimes you'll launch off the bumps instead) so be ready to stomp and ride away clean at anytime.
Make sure you have sharp edges and enjoy being addicted to speed.
