I went with the Pitbull Mini that comes with an Akita Cable, and an extra Akita Cable. So if its close and small I can get the U around a pole, rear wheel, and seatpost. Then I have 2, 4ft cables to tie in front wheel, seat, or whatever... the ends of the cables will thread through the eye for quite a reach.
