    Can you take pics of the tarp ends?

    I just went out, unstaked the sides, and snugged it up. It seems ok until I stake it out. Could this mean I'm staking too far out, and pulling the side seems to the point that they pull the ends closer?

    I get something similar with the Expedition tarp regardless of how I have it rigged. I works a lot better with a nice tight continuous ridgeline but it's still far from ideal. The "asym" shape doesn't lend itself to a very nice tight pitch. If it were an actual square or diamond shape it would be better from a pitch perspective (and being cat-cut would help immensely).

    For now, just get everything as tight as you can (within reason) and it will pull out the majority of the flap. So long as the wind doesn't blow your tarp away you'll still stay dry. Good luck.

    It seems to have a little less flop after tightening it just to the edge of my comfort zone. It's no where near as bad as earlier.

    I don't think that whoopies are a good solution on a tarp. You need to be able to put some tension on the lines and whoopies don't allow that. Figure 9's and Tarp Flyz are a couple of implements that may help in getting the tarp ridge a little tighter whether you are using a continuous ridgeline or tarp tie-outs.

    The last pic looks like your tarp is tied off to the same biner as the hammock. Try rigging the tarp seperately from the hammock and see if that helps. A continuous ridgeline (a single cord) for the tarp should help as well. Put the tarp over the ridgeline so the tarp is supported along its length.

    You could also try just pitching the tarp over your ridgepole on your stand, and tying off to the ends of that pole.

    First, non-cat cut tarps are more difficult to set up nice and taught. That's why there are so many cat cut tarps...
    Second, the asym tarps are even worse for keeping nice and taught as the force vector's don't exactly counter each other.
    Third, it needs to be suspended separately. Get rid of the mitten hooks and plastic ring. Tie directly to the tarp pull out and the trees, not the hammock suspension. Keep everything else off of the hammock suspension as well.

    When you tie to the trees it needs to be very tight.
    The guy-outs also need to be pretty tight and play with the angle to get the lines of force as nice as possible.

    The problem is that, eventually, it will stretch and get the slack back. You can use tensioners to counter this. This will also happen with a continuous ridge line set up. These methods will lessen the amount of slack but may not totally get rid of it; it's just a matter of the design.

    Here are a couple of images to illustate...

    My asym tarp over a DIY hammock; notice it is tied to the trees and guyed out pretty tight, yet it still has a little slack.


    Another shot with a ridge line that is a little short; notice much more slack...


    By comparison here is a cheap poly tarp that is square, not asym; see how nicely even this cheap tarp pitches?
