I am new to wake surfing. I recently bought an 06 Launch 21V that says "Official Gravity Games" on the side. It has a long sac in the center that I'm guessing is about 1000lbs and two small ones in the rear lockers. I'm assuming that they are all stock but I'm not 100% sure. I've tried several different ways but we haven't been able to figure out how to make a wake good enough to let go of the rope. What do I need to do??? I'm getting frustrated by watching all of these youtube videos making it look so simple.
