Need to decide on bow ballast

Since I'm getting two 1100lb sacs for the v-drive lockers I'm going to obviously need some bow weight. I was thinking about the 1000lb open bow sac (obviously wouldn't fill it all the way) but I was also thinking about getting two 400lb sacs. I see some benefit of having two 400lb sacs to split the ballast if needed...maybe one sac in the bow and the other on a seat on the side of the boat. Any ideas?

If i recall looking at the XLVs you have a HUGE locker under the play pen. Id just go 1100 in there. Then you can just not fill it all the way. I would realy stay away from putting bags on your seats.

I got the 750s in the rear and 400 wont allow me to plane. I have to fill my nose bag before i can plane the boat out. Its right around 1K in the nose
