I think the Wedge is fantastic and I use it when I ride with just the stock ballast. I also think it would be great to have for resale value.
That being said, we just did a TV shoot last week and we had so much weight in the boat that the Wedge wasn't even necessary and all the pro riders were stoked on the wake without it.
I was especially proud when Mike Schwenne made the chest high gesture and pointed at the wake while he was riding. When he finished his ride, he said, "That wake is absolutely huge!"
