Well I made it through the night without having to amputate the thumb, so I guess I'll survive. I've done this sort of thing before, but it was usually with smaller coil spring traps. Man those new #4 long springs are strong. Had my wife rolling on the floor when I came in and told her. I'm doing these mods for a friend and I'm going to make sure he wire brush off the dip before I start tinkering on them again. And Yes Tom, it does wake you up.
