Started surfing my quad in some super nice waves lately. Yet I am struggling on it. 50% success rate on sucky waves. Once I'm on them the board goes crazy good. My problem is the tail sliding out on me. I have been told to change my angle, as in don't set up bottom turns like a thruster. Yet I just don't get it. Why does it slide out when it should have more hold. How do you change your style after 30 years of being on a thruster. I thought after some of the beatings I have copped,I should have learned. So some help please
