the number #3s are a much better trap insofar as they have bubbled jaw tips, welded pan, rounded jaws, etc- as good of an "out of the box" coyote trap as the higher priced ones. For the record, its a terrible coon trap staked in the open-you will get lots of chewing.
if you want a top of the line 1.5, try the 1.5 specials- again, rounded jaws, etc. I have had some problems, with the rounded jaws and coon in the water on slides. but on land, you cannot find a much better 1.5
