I'm not an expert by any means and have only been road riding for a year. Mostly I'm a mtn biker.
Anyway, I have a Craft base layer top that has served me very well. Craft makes some good items. I just saw a nice base layer from Specialized at my LBS. I'll probably buy one of them to try, also.
Can't offer any help for the tights.
Good luck shopping and with the Century!
