Recommend race clothing for a HEAVY sweater

I'm searching high and low for a good 2 piece outfit to wear for my upcoming long course (HIM & IM) races but I have one main concern: water retention.

All of the sweat/moisture/water wicking clothing I've tried never seem to work well. I sweat A LOT, and they all QUICKLY become drenched, heavy and annoying. I know that over time, and as much as I sweat, that every material known to man will eventually become saturated but I'm looking to find something that will remain mostly comfortable and not too heavy.

I'm looking at several different things right now including 2XU Comp Tri Singlet, Louis Garneau Men's Elite Sleeveless Tri Jersey, De Soto Men's Forza Tri Jersey W/Skin Cooler, etc for tops and similar products for bottoms. 
 
I need at least 2 pockets combined (top+bottom pockets).

Any advice?
