Well that makes me feel better
My problem with trying to loop the 13m 2011 XB on Sunday was that it would end up pulling only in the bottom half of the window, so there was no lift and the pull was completely horizontal. I got several back-roll kite-loops down, but they were LAME... just a few feet above the water and total body-english to get around.
I did do one that was felt super-slick - timing was spot on so it was really smooth. Felt like I imagine low, unhooked back-roll kite-loops would look. Just one though
Considering that I learned them on the Speed3 21, and have to be careful cos it's so slow... the lift you get can pop you up a couple of meters but there's no kite above you to catch you
My first attempt at a kiteloop was a 16m XB... 2010. Got rifled straight down into the water
