Well, I tried to keep my response a bit more compact than yours.

Let's admit your tires are only going to last half as long as we in the 'lower 48'.
So, your choices are winter tires for half of the year and performance tires for the other half of the year.

Personally I am always anxious to put on the P-Zeros when the weather is warm enough and switch to winters when necessary.
Considering you will get the same mileage out of each set, you can buy two sets now, each of which will last twice as many years if you drive them half the year.

And the best part is they are both optimized for the conditions.

Up to you.
