@ Juany118 -- Cool kayaking vid. I'm more old fashioned. I explain our VT/WC in terms of skiing the bumps. Something I did hard in my youth but had to give up decades ago due to injuries. Loi lau hoi sung, Lat sau jik chung really applies when you hit the moguls hard. And Centerline? Track your opponent relentlessly. Yeah you better face the fall-line or you're toast!
