Brent- I just bought a 2001 X22 a few months back, and this weekend was my first ride behind it... but here's what I can tell you about it:
First, I am an experienced wakeboarder...and have ridden behind pretty much everything out there (other than the new X-Star, dammit!).
In short: the X22 wake is good, but small (even with the ballast full). Shape is not rampy, but not steep...right in between. It is a buildable wake and has good pop, but you'd be adding additional fat sacks.
The longer version:
Sizewise, the wake is not very big, even with the ballast full. But the shape is just right...and that's what's most important. I usually run with a big crew, so will have a lot of people on board and don't think size will be a problem. But for the days when it's just a couple of us in the boat, I'm going to throw a couple of side-sacks in addition to the ballast-- that should get the wake just about right.
As far as the wake shape (in comparison to other direct drive boats), it is pretty rampy, but firm. A rampy wake (v-drives) is good if you want to build it up -- you can get a rampy wake bigger (if you have the space for more weight, this is a problem with a lot of v-drives). If you have too steep a wake, it will break to white-whitewater with weight. Most direct drive boats have a steeper wake. Most v-drives have a more rampy wake. Rampy can accomodate more weight, but a steep wake will give more pop (this all comes down to personal preference).
Generally, the flatter the bottom of a boat, the steeper the wake will be; and the more V a boat has, the more rampy the wake will be. Not always the case (the X-stars and Natiques, for example), but generally...
Without rambling too much, the wake is very similar to the wake behind the Moomba Mobius V. You can probably find a lot of reviews on that wake (check the discussion boards at
www.wakeworld.com)...the hull shape between the two boats is also very similar (except one has engine in back, one engine in the middle). It is one of the cleanest, firmer wakes I've ridden, and the X22 wake is nearly identical.
Good luck with the purchase!!! If that is the boat from boattrader.com, it has been online for a while, and you should be able to talk them down a bit, just FYI.
