I've been doing a bit of research lately about a shelter purchase for some upcoming backpacking trips. I've previously never compared ultralight options, as I'm just now re-evaluating a lot of my gear and making changes. Of what I've seen so far, my interest has fallen primarily to a set up of:
GG SpinnTwinn Tarp + Alpinlite Bug Shelter 1.0
—vs.—
ZPacks Hexamid Solo Tarp + Hexanet Solo Bug Shelter
If my math is right, the GG setup comes in at ~19oz and the Zpacks quotes theirs at 10.9oz. The ZPacks is undoubtedly lighter, but also $135 more costly than the alternative. I've read some great reviews on both. Any recommendations for someone just starting out (even if it's a setup other than these 2)? The shape is quite different between these, does one have an advantage over the other in terms of resistance to heavy winds/rains? The SpinnTwinn seems so open – I feel like I'd be fairly exposed to rain etc. I have zero experience setting up a tarp and choosing a correct pitch, and I've read many times that greater skill/experience with setup is the key to preventing most bad weather issues. I'd say for the most-part I'm a 3-season hiker, and Yosemite/Zion are the next two trips I have coming up pretty soon.
