I have never used a jump trap, but I knew a trapper who did. The ones he was using were #2 jumps I think. They set nice and flat, he didn't even bed em. All I saw him do was find a pile of chaff in freshly combined soybean field, kick up a U shaped backing of chaff, set a jump trap at opening of the U, kick a little chaff over the trap, pour some bloody looking lure on the backing and he was done. He caught coyotes too. I figured that if I was gonna do that, I would use #3 jumps instead of #2's.
