have one, love it!
don't use the wedge but got it for resale value. It adds something to the wake if you don't add any ballast besides the stock. I prefer it without the wedge.
front ballast is a must, you'll just end up adding your own if you don't get it, I find I could use more up front.
here are a couple, I've got more, let me know if you want to see them or anything specific.
http://www.dizzyg.net/photos/thumbnails.php?album=search&type=full&search=vlx we tried surfing once but don't have the wake totally figured out just yet. So far we've had a max of 3 people in the boat while riding and the wake is outstanding.
We've been running stock ballast plus another 250-300 in the nose, 450-500 in each locker and no wedge around 24-25MPH. The wake is really nice.
