I started with offsets ...state law. Now I've found that, especially with the wide offsets of some factory traps I have very little foot damage. There is a lot if difference in oppinion and experience with offsets and foot damage. If you don't have to, I recommend a complete study. I'll still offset mine.
My #3 dbls are the same jaw spread as my #2 coils; or dang close but what ever your state regs are. I've had so little foot damage do to chewing, and that was a cat, that I don't even consider it. I don't have Reds, try not to catch the Grays and Kit fox and have absolutely know experience with coons.
I use a lot of drags. Set preservation is really a side benefit for me. I mostly drag to get the catch hidden and / or not worry about stakes pulling. The critters seem in better shape on a drag...they head for a tree if there is one; shade, springing hold and some thing to chew on.
You've got to wonder about remakes after reading the forum threads. With a drag you have "fresh" soil to put a soiled trap into unlike a staked set where everything smells the same. Conventional forum wisdom says you probably will be better off using a clean trap in clean dirt. Well I've been putting draged traps back in remakes since I started and on very few instances do I ever notice a problem. Go figure. Let me say this, just a few weeks ago I had such a set. After a remake, a coyote visited the set and didn't show the decencey to step on the pan. It rained that night / next day. At the next check the trap was dug at. The actual particulars are hard to know but, when it was dry no diggy, wet diggy. This is, at least, consistent with increased olfactory sensitivity associated with moisture.
