Trade: Zipp 606 for Zipp 404

I have a pair of 2006 Zipp 606 Shimano 700c tubulars I want to trade. They were only used every now and then for racing and have about 500 miles on them.
I want to trade them for a pair of newer model Shimano Zipp 404’s tubulars in good condition. I’m hanging up my tri suit and I’m just cycling now, so I need a wheel set thats more friendly toward road races/crits.

Thanks,
Corey

I have a pair of 700c 404 tubular but I think they are the same year as yours. I would trade them though
