I've rode through most of the last two winters on my slicks. It was harrowing, and at times forced me to take the bus (fresh snow, lots of ice). I decided to invest in studded tires. The LBS steered me towards the Nokian A10s. They seem to be a solid choice as an urban commuter, though I'm entertaining thoughts of asking to swap to the W106s (comments?).

Both Peter White's website and Nokians literature suggest that one avoid "aggressive" riding to prolong stud life. What does this actually mean? I ride fixed, so the LBS said definitely don't skid. Does this otherwise mean "avoid potholes and don't jump curbs?" Or is this an admonishment against speed on plowed roads? I like to spin and go fast, so I'm hoping that isn't the case, but I have zero experience with studs, so any advice would be great.

Edit: This might be better served in the winter forum. It probably is, but as an everyday bike commuter this was my first instinct. Mea culpa, and feel free (read: please do) move if I'd get better responses.

TL;DR: A10s vs. W106 for an urban commuter; can I still go fastish on clean roads?
