I'm a big wool fan, but primarily for cool and/or damp weather. Most wool jerseys are too warm for me in 60+ f temps. The exception is my Smartwool "Rambition" jersey. It's "micro-weight" merino, and is great from the low 50's to mid 90's. I have gotten sunburned through it though...

Wool sock are the best, regardless of temp. And one thing about wool that no synthetic can match is its "anti-skank" properties. I can wear the same wool jersey or base layer for a week of commuting and training with no problems. Synthetics (polypro in particular) are good for one day, tops, and then they go in the hazmat bin. But I'm one of those who perspires heavily, regardless of temp. If ya don't sweat, "plastic" may work ok for you.
