I try to wrap one of my chains around the battery on my RadRunner Plus. I have all ABUS chains. The 1060 metro (is a beast) has a good length, and ought to intimidate anyone getting close. I also have the 6000 & 5600 series flat chain locks. I find the 5600 works best to just chain a wheel, either wheel, not much more. I've got one of the ABUS U locks on my next "to get" lists. I've also added the HEXLOX system to my bike. Front axle, seat post, and some other misc. buttons. I put a couple on my handle bar.
I watch for safe locations, loading docks have camera's and usually a quality railing. I find the fronts of many professional buildings, have PRETTY, but very crappy bike racks.
