So, as the ultimate silliness, I am a non-tarp camper, who carries a 6 ounce 2009 MSR E-wing tarp as her emergency shelter while day hiking, combined with an AMK bivy. It's raining, and I've got my kit spread out around the house, considering whether I could deploy said options when it counts. I hike in the Cascades and the Olympics, on-trail, but even though it doesn't get super cold, 50 F plus drizzle can create hypothermia conditions. I am trying to balance low-weight with actual usefulness, with the idea that I hope to never have to use it.
A couple of questions to experienced tarp campers:
1) I've read Ryan Jordan's Tarp Camping for Inclement Conditions. Should I pay a penalty in weight, and get a square tarp for more usefulness, or is the hexagonal shaped E-wing an ok bet, since it is only 6 ounces, it's for emergency conditions only, and I hope to never have to use it? 6 ounces + 3.5 ounce for the AMK bivy + lines and stakes(3-4 ounces?) + 2 ounces for polycryo ground sheet. The narrowed sides look to me like they won't cover very well in rainy/windy conditions.
2) The E-wing has only 6 tie-outs around the perimeter, plus 2 tie-outs along the ridge-line. The ridge-line tie-outs confuse me, I'm guessing that they should be tied upwards to a tree? They put cord on those two tie-outs, and nowhere else on the tarp–huh?
3)If I kept this tarp, would I want to try to create additional tie-outs? Along the perimeter, or within the body of the tarp?
4) For the ridge-line, would I want 1 really long cord running inside the tarp, or 2 shorter cords tied to the front and back? Looking at Ryan Jordan's article, I would install short loops on the 4 corner tie-outs, then 72" on the front and about 36" on the back, to be looped around trekking poles.
Or, should I just say screw it, and spend $185 for a Hexamid Pocket Tarp? Better coverage, low weight?
I've tried to do a "Save image as", and download a photo to put into this thread, but none of the images seem to want to download.
