IMO the choice of a tarp is based upon what hangers are used to and enjoy. Before hanging, I went from tents, to TarpTents, to the smallest tarp I could while ground camping... because I enjoy the openness of my surroundings. For me, sometimes even my MacCat Deluxe is bordering on too much, and most of the time will be using my MacCat Standard width. I've been through some real storms with both of the MacCats and can't see any reason to be more enclosed. But then again, I sleep with no tarp at all when conditions permit. Tarps are probably the main HYOH item for each hanger... and each individual should choose based upon his own wants and needs.
