Information about different Standard and Setback mods:
When you go across the waves with a Setback (or some say cut-back) prop it is LESS LIKELY to come out of the water. You are side by side with another boat of equal speed and set-ups but he doesnt have a setback. When you cross those waves you WILL pull on him as your boat is more hooked up.
It will give you the effect that the boat is more sucked to the water.
You will also notice that your boat will handle better in the turns due to it being more attached to the water.
