Also are you just flat out making more turns going down the same run as your friends. They make 5 linked turns/carves you make 10 linked turns/carves??
My kids bomb, I'm technical, I make many more turns then them. Partly as I don't want to wipe out and I carve a lot more to where I feel I'm at the edge but still in control. I keep pushing my speed little by little as my skill progresses as well
