yep, those are the ones I run. They kick azz. People say that you should check the nuts on them to make sure they are tight every time you take your wheels off... well, I have been for more than 3 years now and my torque wrench always just clicks. They haven't loosened up a single ft/lb, so far as I can tell, in 3 years. I keep checking them tho.
IMO, they are only "unsafe" if you don't take the time to check them on occassion.... just like wheel lug nuts and the nuts on your u-bolts and stuff... check them frequently and you wont have any probs.
Having the front/rear track equal is a very good thing IMO. Wider is better with respect to stability sure, but more importantly your front and read tires will follow the same lines when you're offroad. Back when I had different width axles, I used to get annoyed that I'd have my front tires going where I wanted them but when the rear tires would get to the same spot they would be slipping/sliding in/out of the ruts the front tires were running in.
