I have a set of the Top Contacts and have ordered a set of the Marathon Winter Plus, and had previously owned another set.

I got the Top Contacts a few years ago strictly for recreational riding so I wouldn't go out if the conditions were bad.

I got a new job this Summer and have started commuting a couple times a week 20 miles each way. About 14 miles of bike path.

My thought in is if I am commuting there is a greater chance of unexpected snow or ice and the studded tires would add a bit of safety for those times.

Anyone go through a similar process? Comments on your experience with either of these tires are welcome also.
