The tradeoffs are substantial. I've come across a lot of through hikers over the years. The featherweight packers are usually the ones who are mentally broken, as if enduring solitary confinement in a cell that has a serious water leak and freezing temperatures. The heavyweight packers are physically broken but still bear a resemblance of a civilized human being.
