Ooor... just learn to ride the the proper position.. Soo many people I've seen out there bending over and reaching for the bar with legs bent.. It's NOT the way to go! Not only does it look terrible (Yes I will from now on refer EVERY thread to the "don't-look-good-while-you're-kiting-thread") it also damages your back like hell and will set you back in terms of performance and safety..
I used to have the same problem back when I started kiting... Had hell of a pain in my back after every session because I was reaching for the bar at max depower. Shortened the centre-line.. problem solved..
Especially thinking about the bow bars where you have to be Goliath to reach the bar full depowered (I am David so this problem doesn't affect me

) Mod 'em and you'll have a more pleasent time out there
