I think Brad & BWinters nailed it. Personally I’m in continuously above average shape for 49 (but not where I know I could be) and know my body well enough to know that lighter boots & cardio are where it’s at for me. This item or that item won’t really make a difference if my finger tops are sweating. A lighter or more nimble rifle might make that alder choked hillside a bit more bearable but honestly that’s gonna be terrible no matter what. Alders, after all, were hand planted by satan himself.
