and what's your rationale? If not, what's your rationale?
The weight of the lock is worth not coming out of a supermarket to find my bike and everything on it gone. That would be the worst. Even though rural France has felt extremely safe security-wise to me while touring. If there are any bags/goodies on the bike then I would still leave it in a place where you can keep eyes on it every 30 seconds. Often when going in to a supermarket i would wheel my fully laden bike into the entrance foyer, or inside the shop. Cheeky, but it gave an extra layer of protection in my mind. I've been tempted by the thin ziploc things, but they just seem too flimsy. A heavy D-lock is overkill. At night strip the bike of luggage/goodies and lock it either to something solid or next to the tent in a way that if it is moved you will hear. Some people recommend a tying line attached to the bike and into your tent.
yeah
medium cable lock
