I'm afraid that the mini will be too small to lock my frame to posts around town. Oh, and what are some tips for making them last longer? Some reviews talk about the keys jamming and whatnot. Will putting WD-40 in the mech every month fix that? Enlighten me.
Should I use Sheldon Brown's locking method to make more room for the lock? Because I'm afraid that if I go through the rim + a seatstay/chainstay, there won't be enough room to go to the pole.
Forgetting the fact that I don't leave my bike overnight anywhere, I don't really live in a high-crime area. I've been using a crappy combo cable lock for years and I've been fine, but I just want a bit of extra security.
If you live in a low crime area, I think any Ulock should be fine if you use the sheldon brown method. Pretty much any lock can be cut with a potable angle grinder, they just are tougher to cut than normal cable locks. Make sure you get a cable to tie the front wheel to the lock.
