I'm non small. Core strength. Down climbing. HEEL HOOKING. Core strength. Do figure 4 / 9 in the gym. Use your extreme reach rather than suffer from it. Follow / TR. What works for us non small folks is not what works for dinkys. Forget about them, and TR or follow the piss out of something(s) hard until you develop the bizarre kinesthetics required for leading roofs when you're too tall for some of them.
MF is really hard when you're tall, and NEVER go near PT Phone Home.
