Got a new expensive bike so I'm shopping for a lock. Should I get a light lock like the Palmy aluminum u-lock or a good lock like the OnGuard Mini Bulldog u-lock?
In favor of the light lock, I figure ain't no lock gonna stop a skilled thief for more than a few minutes. Lugging around a "good" lock that weighs as much as a spare frame is only gonna make me feel entitled to "fahgettaboudit" and lull me into a false sense of security. You gotta defend that sh*t with your life, especially because locks don't do nothin about component theft and vandalism. Therefore, the purpose of the lock would be to simply give me enough time to grab a jug of milk while the thief is looking for his mini jack and, for this, two pounds of hard steel is probably overkill.
On the other hand, I'm concerned that even though something like the Palmy would resist cable snips and perhaps fool unsuspecting thieves into wasting time reaching for their mini jacks, it might actually be so weak that casual thieves could actually pop it open by using the frame as a lever without any tools whatsoever. I'm just looking to keep the honest people honest, which means the possibility of theft without tools (or with tools you might find on a leatherman such as cable snips) must be eliminated.
What do you guys think? I should also mention that I'm using detachable pedals to eliminate the possibility of ride offs and at least take away the opportunity for thieves to steal a fully complete bike.
