Forgive my density, all the searching I did did not really answer my particular question.

What are the actual differences between the Bulldog and Pitbull locks? I am looking to get a mini lock. The only difference on the onguard site is that the Pitbull weighs a little more and looks slightly different. Also, in this low to maybe moderate risk area I live in, would it be worth it to carry around the almost twice as heavy Brute mini? I'm not really worried about price, but wanted to get the most practical lock. Seems like buying any of these locks would give me coverage that would buy me a new bike.

Thanks!
