I thought I'd share an idea.
Although its not really too big of a deal, I don't like having to get a 3mm and 2 mm wrench out when I want to remove my center shock to remove or install my batteries. So I devised a way to make the attachment tool-less.
(1) 8 mm x 2 mm FH metric screw
(1) 2 mm knurled metric thumb nut
The yellow in the picture represents the thumbscrew. The magenta represents the FH screw. Rough up the bottom of the shoulder of the ball in the shock end. Insert the FH screw all the way into the ball and tighten them against each other. (I used a FH screw to allow the shock some articulation) Then use the thumb nut to secure the shock on the other side. The rough surface of the ball against the CF mount allows you to tighten the thumbscrew without having to use a wrench.
