Hope the length/detail didn't scare anyone away!
Anyway, tested some sticks this weekend w/ the Skeeter Beeter. It has a bit more netting that the Switchback, and I think the added grosgrain strips and the tautness of the ridgeline exit point where the stick crosses the netting will add some needed stability. The elastic strips on the Skeeter are definitely easier to work w/ than the grosgrain loops on the Switchback, so I think replacing them w/ adjustable shockcord loops will work like a charm.
Also tested knot size using larks-headed zing it, will work fine as a stopper. Now to locate something to use as the rubber gate.
