Welcome to Arboristsite
Streyken, first, Welcome to Arboristsite. Second.... you coming on here and surfacing with this stuff, it's like the discovery of a lost tribe of tree men. You're kinda like a whole new treeguy specie, yet, we're still kin. Are there more like you? Take me to your leader......
Let me bring offering of how to handle a macrograb, the adjuster you described as unimpressive.
Except that with this particular adjuster (Petzl Micrograb), the difference between 11 mm and 13 mm is huge. If you go up to a larger Macrograb or a Gibbs ascender, then you lose the smallness, that ideal 'palm' size hand feel. The IDEAL, and I know this because of my last three rope fliplines, Vector, Velocity and Blaze, all 11 mm have performed excellent with the micrograb. It's precision control that brings joy, but these 11 mm lines lack stiffness and general uncuttability. We need an 11 mm wirecore combination rope flipline. Enter Netline.
I can see where the micrograb would be undersize for your wirecore (multicore?) We need
11 mm Netline. We could usher in a new era of high-end flipline if it's tensile is up to par (and it is). We just need to politely ask the netline manufacturer 'what can be done'?
Stryken, you've brought us a most
excellent gift.
