NY lock is good if you really want a U, but to me it's so heavy I'd rather just have the chain around my waist than that thing in my bag. NY Fugghedaboutit U is about as good as welding your frame to the rack, but definitely too much weight. Think like a hiker, put the weight on your hips.
i have been known to carry the fuggedaboutit and ny lock at the same time. but thats cuz im you know. hardcore. and stuff. yeeeeep. thats me. hardcore.
