My little experience= 2's are faster, smaller bed, lighter weight, cheaper, and just as efficient if set up with proper pan tension. The downfall is that they are less versitile (in some ways). For example you could use 3's for beaver also, but then again 2's could be used for fox, mink etc.
I'll keep my money, guns, ammo, and health care; you can keep your change
Because you are only allowed 1 bobcat, make your trap choice based on coyotes. They will be fine.
If I am strictly setting coyote, I set my #3 Montana's. You will get lots of trap size opinions, sift through them. There are a lot of good trappers on here that know their stuff and will not steer you wrong.
