Winter Use: Redline Heavy or Lightweight

[H4G64T]

Okay, need to order this tonight, got STM's site up right now ready to buy one or the other. I just completed the AWD swap on my Spyder and while I do not plan on driving the car a lot in the winter, I may need to move it around the driveway or drive it to my buddy's garage to do some more work there.

I need to know, for those in the cold climates, how bad will driving with the heavyweight be.

The heavyweight is really only necessary for extremely shock loaded transmissions/diffs... The lightweight is really very effective, and won't be as bad in the cold.
