We're running an XLV and any combination of tube or rider causes slipping in the corners. The kids like the whip on smooth water and I can't get the backside to stick long enough to get them around. Even doing a couple of quick hard turns to get them outside the wake will cause the slip. When pulling a couple of heavier riders on tubes it's noticably worse.

I also find the boat sticks the corners better doing a left turn over a right.

Is this prop related or the general design of the competition hull?
