So a couple of years ago I bought a 98 outback, the family and I have had great time but now I think its time to put a tower on it! I have narrowed it down to the Aerial Airborne http://www.h2osportswarehouse.com/v/...irborne-pa.asp or the Big Air Vapor http://www.bigairwaketowers.com/towers/vapor/. I was wanting to know if anyone has any experience or input on either of them? These towers are almost the same design and the Big air Vapor seems to be a couple hundred cheaper. Any input on durability, shakiness, or whatever would help me make my decision. Also whats the "install it yourself" skill level 1-10?

I appreciate the help!
