bridger or duke CS traps?

I plan on trapping some problem coyotes in central saskatchewan (predominantly farmland area) and was wondering which of the 2 brands of the #2 coil spring i should use? any tips?

Use #3 Bridgers or possibly #4 Square jaw Dukes. The #3 Bridger was passed for coyote in Canada. The #4 Duke is an exact copy of the #3 Bridger, only better quality.

Currently there is no #2 coil that is legal in Canada for coyote use. This could change in time, but be smart and buy what will be legal for use in 2007 and beyond. The #3 Bridger is legal, the #4 Duke is not yet legal as it is a brand new trap, new to the market.
