I'm leaning toward using one of these two bear canisters for my 2020 thru-hike, for ease of use (no bag-hanging hassles) and for doing my part in potentially keeping a few bears safe.

So... looking for feedback from "experienced canister users" on what size canister to choose.

Initially thinking to base my choice on needing to store an "average" 4-day food supply, plus toiletries/scented items. But should cook pot, stove, fuel also go in the canister? Thinking "yes", and with that, also thinking the larger BV-500 is the way to go, especially since the 500 is but 6 ounces or so heavier than the 450. Or is the 500 overkill?

What say you, bear canister veterans?
