I'm trying out the Sportman Guide 12 x 12 tarp (in white) to see how it will work out for me as a spare . (can't go wrong with the price huh? 30ish bucks?) It's a diamond configuration and the ridgeline length seems to be a bit on the long side. the sides also seem to be a bit too long as well. I prefer the rectangle type tarps with door ends, like my speer swt, it just has better protection and I wish this sportsman's tarp was a rectangle, oh well. pics will follow as I try out different camping spots this summer. It might just end up being a spare tarp to cook under or just hang out under when the conditions apply, like this summer in upstate NY where it seems to be raining every day!
