Oh what a pack that would turn out to be. Squeaking & squawking in your ears all the time, rides so far back it pulls your shirt up choking you while allowing rain to get all down the back of your neck. Probably bounces at the waist too. The picture of a whining, choking, crying & kicking kid becomes clear.

Then again, if hiking with your significant other, you may get the, "Give [it] here, you're not doing it right!" and not have to carry the pack at all.

Either way, still have to decide on which is best for you.

On the serious side, I could quote the rest of Glenn's post. All good advice. Myself, I'd carry the extra bit of weight for the more comfortable wear.
