Replying to How to train skiing at summer on trampoline?

I am new in here but just wanted to ask what tricks should I try to do on a tramp at summer. I have one of those selfmade trampskis so I have been able to work on my grabs but after I stomped misty, flat and cork 7's I couldn't find out what I could do on my crappy tramp. I found out that Ski addiction has pretty good ammount of trampski tutorials but there isn't much of harder spins so I decided to ask you guys.
