My pipes are pretty much all the same and I only smoke 3 or 4 blends regularly, so not an issue with me. I just keep the previous days pipes in a 4 pipe case until I switch them out, so I don't forget which were just smoked.
I always have a leather roll up pouch of Luxury Twist Flake in my car. Living in Ohio, that means temps well below freezing. There is also a small Boveda pack in there. I've never noticed the smallest difference in taste. Just my own observation.
