I am trying to decide myself and I do lots of off roading so I guess I need one thats locked all the time incase I get a wheel in the air or mud on one side, and slips in the turns on pavement?

Which one would you guys say for me?

The LSD model has a higher pre-load which is better for all out racing, but the Tru-Trac locks so quick and smooth it really doesn't have any issue's either. I personally have a Detroit Locker and have had no issue's. Other than being noisey it's great and much better than the stock diff.
