howdy wind catchers just wonderin if it would be possible to stack 2 traction kites? ive got a 2m pkd buster and also a 5m has anyone tried this ? and if so how well did it work ?

I've only ever heard of kites being stacked that are the same size and make on top of each other...
The lines to do this can be bought from any big kiting store and usually cost around £5 -£9 depending on length needed.
Don't ask me how its done.. Simple search on the internet should get you the idea though.
