You're correct NCWhitetail. I apologize. I never should've joined in this apparent moron's rant.
This thread will turn out about like the rest of this site. If you actually know something, there will be someone tell you how wrong you are.
Main Trapper,
Try out those 550s, I can tell you from experience that they are your best best. Also, invest in a pan tension tester like Sullivan's. That way, if you do get any traps with a lot of gadgets you will be able to adjust them properly at each set. I like about 2.5 lbs on everything. If I'm using expanded pans, I will go 3 1/2 to 4 lbs. I know that's a big jump, but I don't like catching skunks, raccoons or small cats. The jump in pan tension seems to help quite a bit.
See you guys later.
