I auto X and track my WRX, so I can't/won't run all-seasons. If I had a legacy GT or something, just a cruiser then I'd consider high performance all seasons but even then I'd drive like a little punk in the snow. Truth be told no single compound is good enough to do it all. Due to compromises in tread design and compound hardness/softness all seasons start to falter at the extreme ends of the performance spectrum that a car like the wrx on the east coast will reach. It's too hard to be any good in the summer and isn't soft enough in the winter for any real grip beyond the immediate edges of the contact patch. For people who run them on their car power to you; it's your car and your choice, you shouldn't be too concerned about what other people think and or are doing. For the rest of you that run two sets of wheels/tires that was your choice and if you stand by it that's great; but your logic isn't and probably won't be everyone else's. Different strokes for different folks. The autoX/track season ends in October, so by the first of November to the 15th I try to get on winter compounds because running on cold summers just DESTROYS them. Then around April 1st to the 15th I swap to my summer wheels for the exact same reason, running winters in the 50's/60's eats them up.
