Bravo guys, and thanks for the post!
I had also thought of paulios idea and will use it next time there is calm wind. Looking at the rig just now, and paulio..I think if you just hollowed out the plastic SS screw ball thingy it would fit over the black part of the Cab. push out ball...did you do this?
Fitzy, your solution sounds interesting and I can't wait to hear more.
