Hey guys,
There was a oke that used boost the biggest jumps at Kitebeach CT about 2 years ago. He was doing it on a 9m² Cabrinah bow and weighed in at around 95kg's. I know of a number of good kiters in excess of 95kg's. Its all about momentum and for bigger jumps and better hang time maybe look at powerful kites like the North Rihno's.....
Good luck with the diet Warlock......and see ya on the water!
