Interesting locks if a bit expensive for some models. Sorry, but I have no experience with any on the ones you listed. Do you lock your bike up at one place every day? If so, then you might be able to leave the lock on the rack there and not have to carry it at all. That's what I do with a big chain and small U lock I got from a local hardware store for around $80 (similar to New York Fahgettaboudit Chain). Don't know about your hood, but here in East Harlem I would never lock my bike on the street. Almost all locks can be defeated by a small battery powered rotary tool.
