Dave,
Yes, I've been using the toothed camlocks for a while now. The ones I've gotten from Minnesota Trapline have been very good.
I'm getting my cable from The Snare Shop. It's much better quality than the Chinese junk from most of the other suppliers.
I agree with you on the softness of the Chinese cable,
I've been using more and more Wolf Fang earth anchors for my Leghold traps.
I had a big male coyote actually dig and pull out a double-staked (two, 36" long pieces of 1/2" rebar with 7/8" nuts welded to the ends) 3-N that was set in deep sugar sand.
Unfortunately for him, he pulled it up just as I drove up. I assaulted him with a bullet from my AR (I guess that does make it an "assault rifle"
I carry a small DeWalt cordless drill in my trap setting kit along with an 18" long 3/4" diameter boring bit from Harbor Freight as well as a 2" hole auger that I got from Minnesota Trapline.
I use the 3/4" borer to predrill a hole for my Earth Anchors. It makes driving them MUCH easier and I have yet to lose a critter because I drilled it instead of just driving it.
Driving a stake or an earth anchor into caliche is not a lot of fun.
