That is reasonable since you understand the risks and the downside of the lock and made an informed decision. I guess the deciding factor is where you will be and what you will be doing there. On the rare occasions that I am a major city when on tour I typically just don't let the bike out of my sight unless it is locked up in my room (if I stay in a major city I either get a room or stay with a host).

Major cities are not a big part of my touring and I don't mind walking or using public transit if I decide to do any sightseeing in one.

Also IMO where ever you are, it helps a lot to ease the worry if you ride a bike and use gear that you can fairly easily afford to replace.

I use a light cable lock. When I'm camping or quickly going into a store to grab something, I setup a trap so that moving my bike will trigger loud noise. Also I undo QR skewer, brake and cable, and drop the chain from the chainring. Sometime, I even dry shift the rear so that chain locks up and tie my helmet to the rear wheel and seattube.

If I'm in the city and I have to park somewhere, I'll go to a LBS and have them do a minor service and tell them that I'll be back. It felt safer than leaving the bike in my hotel room.
