As a young trapper it is respectful that you want to trap humanely.A humane kill is defined as one where an animal is rendered ireverseably unconcious in under 3 minutes.My point about the sauvageau traps was that the extra strikin bar may be user unfriendly in cold weather.When we are alone in the woods we must excersise every safety precaution whether it is using a chainsaw or setting a trap...its along cold crawl home.On a 330 body grip trap i use a chainsaw fill too deepen the trigger notch dog for safety reasons.I also attach a 5 ft piece of 3/32 cable to the chain to eliminate some of the tie down wire.Just personal preference.On a leg hold i file and adjust the trigger dog to a hair trigger.Cut down the pan size to allow a better foot catch.Charles Dobbins has an excellent book on trap tune up.Just a few thought on a day where i should be out bvr trappin.Hope this helps.In trappin fur ever..Zepf
