Its interesting how many people say you don't need extar ballast on the X-25, but most of those riders are beginner to intermediate (please don't take offense).
The one vid that was posted was from 2008 of the CX220. I think the OP is right in that there should be easy to find pics and videos of the wake both factory and full ballast and PnP. These boats main purpose is for towing and making a big wake yet it is the one thing that's hardest to find online.
I think it would be to MC's and buyers benefit if there were videos that actually highlight the wake and wave from different angles and not just make it a 2 second clip in a video full of slow motion girls in bikinis and riders strapping on boards on the back of the boat.
2013 X-30, 6.0L with 2500lbs of ballast and 500 lbs of lead.
