1: I'm pudgy, so I don't know what on earth would be pushing hard enough on the trap to make it want to bow.
2: I think that if a trap is properly reinforced, or properly constructed int hef irst place, it shouldn't bow. Thin frames with stronger-than-intended springs will bow as soona s you put the springs on it, or relatively soon after few settings.
Its just got to do with where the pressure is on the traps base. The way I do it the pressure is on the ends of the base, breaking them over your thigh (like my trapping partner does) puts the pressure on the center of the base.
I agree though they should be reinforced so no matter how you or anyone sets them they won't bend.
Thanks for the replies!!!
