Thanks for both of those videos. Hubs is 6'4" and 240, a big wide guy. We currently use a heavy ol' Mountain Hardware 2p I bought back in college. It's gotten a lot of miles out of it, but it's just not big enough for him and I both.
After lots of debate, I think we both are digging SS2. I think I prefer that over the 'front loader' aspect of the rainshadow. Neither of us is the most graceful, so moving the poles even slightly out of 'right in the way' would be a benefit. And I really like the giant vestibules. We're upgrading gear with the goal of a thru-hike in mind.
