Dude, I was at Boulder last weekend and they had two parks. The one on the right has two 10-15 foot jumps. Also a barrel at the top, and lots of boxes and rails. Then there is another park on the right with two 25-30 ft jumps and some more rails.
Oki bought them last year and yes they are heavy but if you have any leg strength you can handel them. As long as you get them set up by a pro you will be fine, anyways line will replace any broken bindings under warrenty.
