Hi all - I know it's a universal Internet rite of passage to ask a lame easy question as your first post, but I swear, I searched for similar posts first.

So, I just started bike commuting to work this month (3 miles, from Cambridge to Boston, for anyone local) and I'm on a KHS Urban Soul. At home I can lock it up inside, and at work I have racks in the office parking garage. I'm currently using a Kryptonite Series 2 U-Lock and I'm happy with it, but I picked up a Kryptonite Hardwire cable lock (keyed) to temporarily secure another bike I'm selling and noticed that it's MUCH more comfortable to travel with in my bag than the Kryptolok.

My question is, does anyone know if the Hardwire is harder to cut through than the cheaper cable locks out there, or would I be a complete idiot for using it instead of the U-lock? I'm obviously most concerned about the rare times when I have to lock it up outside a mall, grocery store, etc. and not home/work. Thanks!
