I have switched most of my prism kites over to the BMK style for that reason... Easy repeatability.
That strikes me as funny. It was the Prism style before it was the BMK style. Prism gave it up cause it was too difficult. That's about the time they started with the sewn in place O ring bungies. Go figure.
The third bridle leg was added to high wind kites by Ken, or was a recommended mod. Helps a lot.
