What size de powered kite would be good to start out with for land boarding on grass? I weigh 170, and would be using it in the towson/Baltimore area.

Imo a 7.5 is a good place to start out...gonna need 12/15+ winds but easy to handle not intimidating like 10m or big ARC can be starting out..I take it you have been doing this fb already?...this isn't a size for going up if that is your end game, for that minimum 9m
