Thanks for the additional details!
I'm thinking of trying kiteloops to maintain better speed as it seems difficult to bring the kite through the upper edge of the wind window in light winds. Good idea? Anything I should be wary of when attempting kiteloops, other than having lots of clear space around, and making sure to have enough clearance to loop the kite? (It's easy on a trainer kite, not sure how it will change on a LEI kite)
Keep the loop high and tight. If you go low and deep it is harder to get the kite back up with out it falling out of the sky. All so don't try to correct the loop. I had a problem with doing this when I first starting doing loops.
