New Polartec fleece is wonderful and much warmer than wool. I have been very impressed with Polatec Power Stretch 200 waive tights, they are very light, very packable, very warm and very breathable. I do not have a Polartec jacket but I own a wool jersey and a t-shirt.
Wool does not smell though and synthetic fleece does.
For winter riding(warmth) I would go with Foxwear personally. Wool is for early spring, fall riding.

I also use eVent Shower Pass jacket that I use for cross country skiing and winter cycling, It is OK for that, but I would prefer more breathable and better insulating fleece jacket than the eVent jacket if it is dry and cold outside. The eVent jacket is great in cold/windy rain though.
