Cliff Outdoors SP Leaf
You don't know how many times we have heard that the Beast box needed an extra leaf to hold more flies. Our thought was, just buy an additional box (Cliff's pretty sharp that way). It was on a trip south and space on the plane was limited, when even Cliff said it would be nice to have a leaf in the Beast.
So a special leaf for the Beast is alive and well. It pops in and out easily, and you can take the SP Leaf out to use during the day and use it as a big Float Patch. Tuck it safely back in the box when you are done -- it's handier than pockets in your underwear.
