Crossed double stack will hold about anything as long as you connect to the cross chain. One stack will pump about 2" and lock up the whole thing, this is a great set up for sand or mud. And as far as pull out go, it is more of a condition or pan tension then anything else, if you are catching them by the pads, then your tension is to light, the bracelet should catch just above the foot and be pulled down to the pads. Over the years I have put a thousand+ in the back of my truck, very few pull outs, sure you will always get one or two, most of the time by the animal stepping part on the jaw and the pan or cover at the same time. Not alot you can do about that. Some of the old Northwood traps had pans that were to big, and I just cut them down abit and got rid of the square corners. This seemed to help with making sure that the foot was more centered before firing.
