These things any good? I already got a heavy chain and pad lock, but id like to get a u lock (flat key of course) to supplement that. I was thinking of the evo cause its a little lighter then the New York u-lock. Also, this would make it more convienient when I took it along on my roadie on long rides outside of the city (I live in NYC) and need a quick and hopefully somewhat secure lock. Also what about the evo minis? they look nice but r they too thin to lock around sign poles and parking meters? Thx guys
