Just curious, but how did you arrive at the 8 sheets of TP per day? What about a compass? Matches?
Trial and error. Actually, on most trips I take 4 sheets and use both sides.
Re the compass: Most of the areas I visit I have been to several times before and am well acquainted with the territory, so don't need anything. If I'm not intimately familiar, I take a topo map and orient it with the surrounding features. If a new area, I take a compass as well as the topo.
I keep some matches in my toilet paper baggie.
