i'm going to assume their all hardened steel, but which would last the longest against an angle grinder assault? when i lock it, its going to be near the street where there are many people walking around so the thieves will attract attention. i want the best for the peace of mind really lol.

i'm pretty set on getting mini u-locks, as i read most u-locks are broken through the bottle car jacks, not angle grinders.
so is the fahgettaboudit mini u lock worth the extra agaist the evolution series? how bout onguards or other brands? i'd like the most cost effective for the money.
