Anyone have any experience with upside down rigs. I've been toying with the idea of one for my 442 and I came across this one from Vega. I don't think I could bank on an elastic restraint.
I think a Null may be at the head of the pack for these rigs (either a SKR or an SMZ)
or I'll troll for a Bianchi 9R1 with a clamshell, but they seem bulky.

Any and all opinions welcome...
