Denny,
I don't have a fat seat but I run a fat sack in the trunk + 225lbs of sandbags.In the bow, I have a 65 lb. snadbag under each seat and four more under the dash.I also picked up some "suitcase" type tractor weights(100lbs. each for the side storage).The wake is nice.It's no wake like Travis Moye had when he had the 'Yotas at Ride the Spot,but friends have been pulling all the tricks where you think a huge wake would be needed.
Post some pics of your new ride!Welcome to the Epic family.Enjoy it!!

If you do decide to use sandbags,wrap them in trash bags and tape them up so you don't get sand everywhere.
