Probably having a lot of "throw" will help tremendously. Some older bars do not allow a lot of throw, i.e. amount you can flag the kite out.
Other thing, and I won't tout the brand I purchased, is to get some new kites. Or newer if you can't afford new. I upgraded to 2017's & man what a difference. The things are wwwwaaaayyyyyy easier to control in all aspects!!!
When I first started I had an issue with not being able to affect control with the amount of throw and a waste harness so I switched to a seat harness.....now I am ready to revisit the waist harness....I got skunt yesterday all eager to try the tips you folks suggested...wind drop to well below >10....started shopping for a 15m...this happens more often than not around here.
