I have been using the volkl wall for the past 3 years and it's a great park ski, but I was looking for a more versatile ski. I have set my sights on the armada B Dog. I am 5' 7" and weigh 165lbs and have used a 177 ski. The B Dog is a more rockered ski and would have a shorter running length because of that. I was wondering if I should go up a size to 182, or stay at 176. I ski hard, fast, and I hit big jumps.
