I could use some guidance on my winter upgrade project.

Planning to run 2 1100 bags in the rear corners of my boat. Each partially full for wakeboarding, or one side at a time full for surfing. I doubt I'll ever be filling both 1100's full at the same time except maybe to see what it looks like at least once!

Would I be better off to share one Tsunami 1200 to fill the rear bags using a splitter and electric switches or just go with two Tsunami 1200's and skip the valves?

As for switches, wiring, plumbing, etc. it will all be custom as basically nothing exists. For the intake I have room and am not afraid to drill another hole in the hull for the additional pump(s). >>I have a Rule pump in there already that will be used to fill my front bag.<<

Cost on this isn't a real big deal but why spend the money, drill the holes, plumb it, wire it, etc. if I don't really have to? Plus I've noticed it seems like the cost of electric valves is almost as much as pumps.

My thoughts are - simpler is better. Oh yeah, and I only wanna do this once!

Advice and experiences would be much appreciated.
