These two links show the breakdowns of the CR reports on passenger winter tires in 2009 and SUV/truck winter tires in 2011....with ratings on wet braking, snow traction, ice traction, hydroplaning, etc (Note: Hankook Winter I*Pike = W409 in the CR report):

Too bad that the Nokians are only available and way overpriced from Kal Tire here in Western Canada...unless you go down to the US.
Interesting to see that the Yokohama Geolander I/T G072 (truck/SUV version of the Ice Guard IG20???) does well in wet braking and hydroplaning, but not as well in ice braking.
As you have said, it's impossible to find a winter tire that is a star in all categories.
Good luck.

Thanks for those links Dave, I'm not a member of CR so I wouldn't have the info otherwise.
Interestingly, the General Altimax has better wet braking and hydroplaning scores than the X-Ice (if I understand the circles correctly, full red = best, upper red, lower red, full black, upper black, lower black, empty in best to worst). But are significantly worse in ride comfort and noise. They are also $34/cheaper a tire in 205/55R16 on 1010. These are quite an appealing choice based on the CR review.
Tortoise: good point on foot+ of snow, truthfully I rarely encounter that much other than the odd parking lot/trailhead. Very rarely am I in a situation where clearance/undercarriage are an issue compared to packed/icy roads.
Heli: Thanks for the thoughts on wheel size. I called a local tire shop (Volco tires, affiled with 1010tires) and the guy confirmed I can run 205/55R16 no problem on my Mazda 3, I'm assuming that includes caliper clearance. I'm 99% sure my car has the same rotors/calipers as other trims which come with 16's stock.
He quoted me a price on the X-Ice 2 that was within $11 a tire of the 1010 web price, and the Pirelli Winter Ice Control were the same as online price. Steelies same price as well ($69.99). Might end up going there and avoid the delivery hassle. Going to see what their price on the Altimax is. No rebate on General's right now unfortunately, handy thread at RedFlagDeals in the auto section lists them (can't post links yet).
safristi: hydroplaning is a reality of the Sea 2 Sky

, it's dumping snow in Whistler and driving rain at sea level. Sucks to hit the standing water in the dark at 90-100KM/H.
