There, are a LOT of barely-used 7000 cu.in. ish "Expedition" packs on the used market and those with bright colours can be muted by using a dull toned pack cover. This, to me, is the best place for a novice to start and thus learn what is most conmfortable for him as all the advice here available, cannot "feel" your what your own body will tell you.
Excellent point.
