Trebor, you hadn't indicated what purposes you wish to use your new acquisition for.
I have an '07 OBV.
My input from an all-sport perspective:
Skiing: -
- At 3000 lbs it is (next to the Sanger) the lightest V-dirve on the market
- Wakeplate helps drive the nose into the water and flatten the wake
- BUT: It is not a Direct Drive and will never perform like one for skiing.
- NB: So if you are a skier, make sure that boat has the wake plate, or add it ($$).
Wakeboarding:
- As several have posted elsewhere, with proper technique, you should be able to perform just fine behind this boat.
BUT: Your riders who go behind other, larger craft, may complain about this wake.
BUT (2): For advanced boarders, at full rope and higer speeds (23+) it won't perform like a bigger boat.
Surf:
There is countless info on this forum as to setup, but you do need more ballast, or some heavy friends, if you wish to surf ropeless.

Ballast:
The only bad advice on acquisition I got was I didn't need G3. Baloney! So I fill 2x350's manually.
- Check with your dealer whether they have the capability to install G3. My dealer does not.
- The do-it-yourselfers on this forum have done it themselves and shared the knowledge.

Overall:
Get it right (type of boat). Moomba/Supra dealers fully expect that their customers will be back, often for an upgrade or different configuration.

Hope that helps.
