First post. For a future AT thru hike, I am contemplating between the ZPacks Hexamid Solo with a bathtub groundsheet & bug screen at 14.3 oz & MLD Grace Cuben Fiber with the bug bivy at 10.9 oz. Should I also consider the MLD Superlight Bivy? I am concerned about the bug screen on the Hexamid soaking up mud. Any alternatives will be considered. Thanks
