"Old hull" Sante ballast options

My question is regarding the old style (2002-2006) Nautique SAN Team Edition factory ballast.

What years were the rear "Wedge" tanks offered as an upgrade? Was there any years the wedge tanks were standard?

Was the center tank an option or standard for all years?

I think the 06 was the only year the ballast was pump fed, Right? Is a pump fed ballast much better and is it really worth converting from a gravity system?

02 team brought the belly tank in and then in 03 was standard. I believe that the wedge were 02 also and were standard from then on.

belly tank is only standard on the "team" edition.

all ballast systems on the 210s are pump fed. the older ones relied on some janky valve system, but there was necer a gravity fed ballast system.

02 210 team and I've got the wedge tanks+belly
