Thanks for the input. We live in Los Anchorage and the dominant condition (for the past several years) is frequent snow followed by warm temps and melting. At best, we get polished ice at intersections; at worst, ice on all the roads.
Having done both, for the Los Anchorage climate, I'd have to give the nod to studded tires over a siped tire and certainly over an all-season...were we in Squarebanks where it stays winter once it decides to be winter, siped or perhaps even an all-season would be better, but in my experience, they just don't work as well for our predominantly ice conditions.
All that being said, my pick-em-up has Blizzaks on it and it does just fine...but the wife has a preference for studs: combining that preference with an arguably better fit for our climate, I'll look into studded options.
Grit....on the sno-go fleet, the one I ride has studs. I haven't yet convinced the GK's or the wife that there's a pretty strong need to be heavy on the throttle to power through curves when driving a studded track. Had one rollover with the oldest grandkid driving, so they're now relegated to the studless machines.
