I carry this on tour:
I slide the shackle through the wheel in between the spokes, including the seat stays inside the shackle. A vinyl covered cable end is also included in the shacle, and the other end is looped around a tree/pole lasso style. I use this for quick low risk situations such as stopping at a flea market or going shopping while on tour. With this combination, the back wheel is secured to the frame, and the bike can't be wheeled or ridden, plus it can't be lifted away. It is of course not too much of a challenge to cut the cable, and a bolt cutter will cut the lock, but the lock shackle is not readily accessible to be cut so it is good enough for me. The removable shackle lock is light weight compared to a D-lock.
Funny, I use almost the same thing.
If I know I'm going to be locking up the bike, I use a Kryptonite-mini.
