+1 for a dedicated stud bike. I used to wait till the morning to decide if I needed to swap wheels on the same bike. That was a hassle when I guessed wrong the night before. And of course, the shifting is never exactly spot on and required a half turn or quarter turn of the adjusting barrel.
Even with two bikes there's still the hassle of mounting the lights and cameras in the morning, but certainly not as big a hassle.
FWIW, I run Schwalbe studs with the two rows of studs, not the four rows. They work well. With the 240 studs (4 rows), you can probably take corners a bit more aggressively, but then again, why do you need to under conditions when need studs in the first place?
I have Suomi W106s as well on another bike, but the treads are more aggressive looking and probably do roll as well. They are also great on ice and compressed snow/ice/slush.
