I've had an X-25 with about 3000lbs on top of the factory kit, sorry no pics but here is what I know. The wake is huge and clean, overall it is more steep of a wake than the X-Star but not as steep as some of the Nauti's. Think of it as a smooth transition with a more defined lip than the star. The wake is very rideable, it is consistent and doesn't launch you goofy. You will not be dissapointed!
The boat we ran had the 5.7L, with this much weight the stock prop is lacking. The boat will still get on plane but you need center trim tab to do so (new auto launch would be helpful, we ran an older boat without it so manually raised tab once on plane). Personally I would opt for the 6.0 or 6.2 if you are running this much weight and I'd still prop it down a bit but that's how I'd run a star too.
