I posted this question in the Weight Weenies forum as well, but this is probably the more appropriate posting location.

I currently have a Time Equipe Pro Featherlite Carbon 1" fork. It's perfectly fine (no crashes, etc.) but it's 8-9 years old. I'm upgrading components from 7700 series Dura-ace to 2010 SRAM Red and I'm wondering if I should replace the fork too? If I do I'm considering either the Easton EC90 SL or Alpha Q GS10. I can get a good price on both forks for the component upgrade (sub $200). Do carbon forks wear out? I'm I wasting my money with a fork upgrade? I weight 170 lbs, but expect to drop to at least 160 lbs. in the next month or two. The Time has a carbon steerer tube and is stated to weigh 395g. The newer forks weigh about 330-350g.

Ancillary to this decision, should I upgrade my seatpost. I currently have a Thomson Elite AL.
