If I was storing primarily indoors with only an occassional foray outside overnight then I would stick with the cotton styles. I personally have no direct experience with the other materials. But, I have a friend in California who stores his 107 outside under a cover, and it is the Noah fabric. Seems to have held up well and so has the car. So, I'd probably opt for the Noah fabric for the conditions you have described. The lock is a good accessory, as you have already learned from experience.

FWIW,
