I started with the standard HH fly and it wasn't long before I got the OES deluxe MacCat. It has greatly enhanced my system for camping. I now have room under it for a gear hammock, can set it up with my leki's for a great "out of rain" shelter, and not to mention the great coverage in a downpour. I stow it separately on the outside mesh of my pack for quick access. First thing up, last thing down! Also had Brian make me pockets in the corners for stowing my guylines. Check out Backpacking light.com for cool little guyline tensioners using aircore line. See my gallery for a pic of my setup.
