To answer a few questions, the gear is a highwing clone. I purchased a set of highwing gear, built a set of jigs to copy the geometry, and built my gear.
As some pointed out I did provide attach points for a redundant,adjustable bunji system. Very simple. Allowed me to use a lighter main spring.
I will have a set of new highwing gear for sale in the future if anyone is interested( used only to build jigs with). Will post in the for sale section when I get some time.
