RE: OK Rage rubber band guys....what size
UNsuccessful test with the #7 o-ring in the spot I had figured (towards the leading edge).
Without the oring on the blades....the blades deploy as the head is pushed through a common plastic grocery bag (taut). With the o-ring in place (original placement cited)....they didn't deploy at all while being pushed through a heavy duty lawn garbag bag. When I moved the to the place the Matts say to put them.....only one blade deployed.
I moved it "halfway"....and they both deployed, each time (5 tests).
I know this isn't "scientific" (at all).....but I found a "happy median", I think. I'm convinced this way will work on a deer.
