750's in rear of xstar?

I was wondering if the flyhigh 750 lb sacks can fit in the rear of the 04-11 xstar? I know flyhigh makes a kit with the 550 in the rear and 200 in the front. I just want to know what the best weight set up in this boat is.

Also what size sack does Harley use in his xstar that runs from the front seat all the way to the drivers seat? How much does that thing weigh?

I am wanting to get an xstar and i will defiantly sack it out. Currently ride pickle fork x2 with the flyhigh upgrade plus 750 running parallel with the boat touching back seat and a 600 running parallel on top of the front seat. I believe that is around 3,750 lbs. So i have a feeling i will be running more in the xstar.

Comments from people that ride heavily weighted xstars are greatly appreciated. Also if anyone in the houston area rides a heavily weighted xstar and wouldnt mind me testing there wake out i would gladly pay some good money for a set.
