I can't say how it compares to the Tige 20V, but it's a decent wake and a nice boat...especially considering the price tag.
A better comparison for the X-1 would be the Supra 20SSV. They have a similar wake with just factory ballast, but the X-1 will have a larger ramp and more mass when you start adding an additional 1k lbs on top of factory.
Keep in mind the Outback V for '06/'07 is the same boat as the Mobius LSV for '05, without the wakeboard pkg. I'd recommend at a minimum, the EFI engine, wakeplate and 3 bag ballast system.
Here's the wake of an '05 Mob LSV with factory ballast and two people in the boat, in about 7-8' of water at about 22.5 mph and 70' rope.
