Has anyone tried the Ribz front packs? I'm 5' tall and small framed, so my goal is to more evenly distribute my pack weight between front and back. 25 lbs on the back of a 160 lb person is not so bad... but sometimes I feel like I could end up like an inverted turtle. I have experimented with adding pouches on the front of my shoulder straps. I liked the more even distribution of weight, but not the downward pull on the straps. With this having its own harness it should hang better. I would put smaller, heavier items in front (food/water/personal/etc) while keeping bulkier items in back. I should be able to change my center of gravity this way. I believe the packs are 12 ounces, but will off set this with eliminating some stuff sacks. Any thoughts?
