Wheels making my head spin

[entropy]

I ride a 2002 Giant OCR-3 and would like to trim a little more weight from the bike. After a new seat, tires and aerobars, I'm down to few choices. I'd like to go faster, but I won't spend the original cost of the bike in new forks. I'm over 40, 193 lbs. and would like to do a few TT's this summer.

Anyone have any replacement wheel recommendations for my stock Alexrims DR13's, that combine strength with lower weight? Yeah, and I want to win the lottery, too!

Thanks,
Entropy
