Macroscien (and anyone else who has an engineering brain)... I am trying to design a simple handle pass simulator for my son at home.
he's got all his surface passes (both ways) and has been moving into air passes all season but can't seem to break into that next level.

While he is getting some instruction from some travelling pros they all conclude he's just not strong enough at the moment. that being said they can't fault his technique.


so, be good if he can at least work on this at home on the basic bio mechanics of it all.

so ... ideas ?


thanks in advance to the Seabreeze crew.

ps I've already got a simple setup on the pergola but it needs to carry a load away from him as per an unhooked kite.
