it's between a few; all of them with the cable in addition to the u lock; Krypto std, onguard bulldog or pit bull. all are silver Soldsecure rated.

I am soliciting opinions on ease of carry and use, and getting clarification on a few other things:
is there a real pronounced difference between the bulldog and the pitbull?

I ride a few bikes, and one of them is running 26x2.125s, and the "ATB" models seem to have more room for a bigger tire. is this needed? is it just overkill?

anything else that I may need to know, I'm all ears. Thanks!
