Although I could likely to smaller, I run 26" stays in all my Kifaru packs simply because the extra height isn't noticeable to me but it's nice if anyone taller than me wants to use my pack. Luke and I routinely swap packs back and forth (sometimes on the same trip), and I have been known to loan packs out to friends as well. 26" is likely overkill for me, but for taller users with heavy loads the additional lift is critical.
