Looking at the pictures of the tyres you have in mind i think i would opt for the Sirac's for winter use. They look to have the most open tread for good water clearance and having a more open tread they should heat up quicker in the cold weather too.

Plus, you already know what they are like and how hard you can push them, something you would have to discover again in the cold and wet of winter if you did change to another brand.
