To be honest, its not gonna get you anywhere past a beginners level wake. The TS6M was built specifically for competition slalom skiing. Although you can adjust the wake plate at the back, I highly go against putting any ballast in these boats. The Transom sits low in the water, as does the bow. To get the most out of it, I just use a small sac in the rear storage compartment, and adjust the wake plate.
I dont know if anyone else has tricks, but thats what I do. Shaun, post some pics of yours.
