Fixed it.
The Diablo manual says to just keep shortening A1 as the lines change with age.
But using the line plans F-One emailed me, I had to add adjustable loops to lengthen B1 and C1 for it to fly right. The manual was no help. I actually used Flysurfer's mixer tuning instructions which worked great.
Now it's predictable, turns quicker, has more depower which means larger wind range and points a bit higher while going much faster! Back to new!
Connor doesn't really show how to stretch them back but I did it by attaching to a snap-shackle and connected to my car. As someone said you can kinda feel how much they should stretch back to and then match that all three are even. After I did this my halo went back to flying like new and I've seen others do this since wiht good results.
