Doesn't sound too big to me. The bigger the better. I currently use the Noah's 12x12 and am working on a an 11' R/L with 6ft on either side. I canoe/kayak/car camp and made certain that whatever canoe/kayak I bought would carry me and my gear around (proud pound hog here ). I want plenty of room to hang out under the tarp when it is raining, because it always seems to RAIN!!! when I go camping.
