well I have a 3m two line foil and a 9m & 12m SLEs. Yes the 3m does pull you around but not very fun for jumping. (I use it in 15-20mph typically)
If you are looking for a kite that you can jump with then i would go for a 6m. That way you aren't strapping yourself in to a freight train. Get a bow or SLE.
Make sure to video your first times using the kite!
On a side note: I recently found a 2001 kite at a garage sale and was gonna pay at most 40$ for it. The lady wanted 300$!!! I told her it was worth nothing and dangerous. She proceded to tell me that she was planning on using one of those leather weightlifting belts to "hook in" and get on her rollerblades in a big parking lot the next day.
I told her go for it. Should work great!!!! hahaha jk.
At least you dont sound as reckless as her.
