Right off the bat I noticed the ski likes to stay planted. Under hard acceleration it keeps the pump hooked up. Almost eliminated the annoying 550 purpose… The grip while cornering is a huge improvement!
When popping off a wake (think jumping a boat wake) the ski tends to want to level out instead of going nose high. I did notice the handlebars do have a slightly stiffer steering feel back and forth.

…I can definitely feel a difference. it hooked well in the corners and i have the whole handling performance set up with it. On straight aways it really kept the front end down more and eliminated the usual slap that 440/550s have. I was happy with how it handled especially with that 750 motor and the 750 pump matched with the extensions, it made it pretty nice and smooth in corners and straight aways. Seems as if 750 swaps cause for the ski to be heavier in the nose and it still did awesome.

The XL extensions are a huge improvement over stock. The biggest improvement was felt in a straight line. The nose of the ski is definitely planted more and porpoising greatly reduced.
