I was on vacation last month in Florida where I have a saddle rigged and ready down there. I have that one rigged with Stable Braid and I promise you, it's no stiffer than regular 13 mm climbing line, and flips the same, IMO.
Yesterday I did a little ascent up a 30' limbless trunk, where you hug the tree with the inside of your knees, shins and ankles, do a quick flip with the flipline, 'curl' yourself up, leg hug, repeat. This is when you're too dang lazy to walk over to the truck to get a throwline and the first limb is a bit far for a monkey's fist. Anyway, I used to do that most impressively when I was on wirecore, but yesterday, on rope flipline, I struggled like a whining weenie. The rope would 'roll'. Wirecore doesn't do that. I use that method, also, on limbless stems up top, but I'm gonna probably not do that up high in the tree; not with the current flipline anyway, not above my tie-in point.
DFD34, you still with us?
