I've got one and like it a lot, but it doesn't seem to get much attention... Not sure why.

The only thing I don't like about it is the plastic D-ring stake loops. I'm going to replace mine with cord loops to make them easier to use. It would also help to be able to pitch it a little higher in the summer for ventilation.

I'm not sure if it makes a big difference, but I pitch it with my trekking pole handle-up in front. It seems to make the gap a little smaller, plus it keeps my handle clean. The tension is enough to hold it in place. Having the tip up and having that little hole might help with ventilation, though.

It also appears that yours has a waterproof zipper... Is that so?

Have you tried pitching it as anything but a fully-enclosed shelter? I like using it as an A-frame in warm weather, but I'm still new to flat tarps and haven't experimented much...
