NeBowhunter: I will give you my 2 cents. I own some duffers, and a few coon cuffs. There o.k. they have there place. They work, they all catch coon, but my opionion after buying some and trying them , they have no comparrison to using the No # 11 or 1 1/2 of your choice.
The Dog Proof traps are expensive and they catch only one thing, coons. I'm not writting them off as not useful I just don't see owning a huge amount of them. I use mine around houses, barns, places you just don't want to catch anything else. I wouldn't put out a whole line of duffers or egg traps, there just not practical, in comparrison, the No # 11 Double jaw or 1 1/2, there versatile, and a much better buy.
