#11 is a tenacious little trap with tremendous holding power by sheer design. stick a screwdriver in the closed jaws and try to twist one open. the design of the longspring allows for very high spring lockups, but coupled with the short distance between the spring eyes on a #11 (with its little, short jawspread) only enhances the holding power. Get some with stout springs and you have a trap that will hold anything that gets in it. I've held a number of coyotes, cats, fox, etc in them, even toe caught beaver. Use lots of swivels. I use #11 both regular and double jaw models.
I also like 1-1/2 coils in water sets or where I may have a potential coon or fox catch. #2s are way too big for coon, unless you use older style #2 longs, which have the same jawspread as a 1-1/2 coil. #2 coils have a wider jawspread than most #2 longs do.
I also like the griz, and the coon cuffs, and I run some live traps where necessary.
