Custom ballast - 3 inlets vs 1

Hi guys,

Have been planning a ballast system for my v210 sanger which didnt come with one.

I have spoken to heaps of people and went to purchase the products, but was told by the guys at wakemakersthey dont reccomend one larger inlet.

Just wanting to see whether anyone had any experience switching from 1 inlet to 3 or vice versa. For me the plumbing would be easier, its cheaper, and a whole lot less hassle due to size restrictions.

Setup would be 1 1/4 inlet into a 11/4 T where one pump is fed, with the pipe off this t split further into the back pumps. Im planning on using Johnsons pumps.

Any comments would be great.
