Offer the 14's for sale on a VW forum in the fall. They'll be snapped up. You get very little for used tires at a tire shop.
Bridgestone Blizzaks always get good press, especially the new REVO1, but treadwear on previous models has not been a strong point (maybe that has changed). Nokians have a cult following and historically have good tread life. I wouldn't hesitate to put some Hakka 2's on the P5. There really are too many choices out there, but these would be my top two picks, based on reports, availability, and driving older Blizzaks and Nokians.
Morty will be able to comment directly on what he offers, and you should consider buying directly from him, as well. In Hamilton, my dad likes TireCraft on Rymal Rd. They carry Nokian, among many others. I put budget snows on my EL, and I don't really miss the Nokians (which were on a Matrix) that much. If the top brands are a little too expensive, there are alternatives.
