they are so THIN!!!, sometimes i come short on a jump and had to land on the flat part. i stick out my tail to absorb some of that impact. it's like a 12 ft drop. i weight about 180 lbs with all the gear. i aint no physicist but 180 lbs + 12 ft drop + whatever speed i was going that must be at least 500 lbs of force on the snowboard. and yet the board just takes it and takes it and still holding it together.
