The vast majority of my traps are full mod Bridger #3 Dogless...but I have about 18 2-coiled 550s. They are both nice traps and I like them equally depending on the set. The spring pins on the bridgers though are pretty much crap. But I have a mod for that. But I am currently trapping a place with a friend and he is running the KO-K9 Jrs with IL/OL and 2 coils. I cant say enough good things about them so far. We trap live market and they have really been kind on the feet and although we have had a couple of them snapped we haven't had any pull outs.
