When you know how to ride, you can adjust to any board fairly easily. You're blaming equipment for your own shortcomings and taking offense when others try to point it out. You will do what you want, of course, but being defensive is not going to help you handle your board better. You've been given a good advice: learn to ride, take lessons.
I'm switching my board out because I don't like the feel of it. Good advice is not saying your probably horrible take lessons. Good advice would be maybe you should try adjusting your bindings, or yeah your going to need to ease up on turning on this board it's really sensitive, or asking what kind of snow do you typically ride on and gathering information to give the best advice. Unless all you guy's are instructors and need extra cash. let's get past the Rocker thing and just say it's not Cambered.
