I'm still not sold on the idea of a front locker compared to a good front limited slip. Besides that obvious pain in the ass of not being able to steer with it engaged, it's very hard on the CV joints, power steering, etc.

A good limited slip, like a Torsen gives almost the same traction as a locker, has no switches to fool with, works transparently unlike clutch-pack limited slips, and you can steer with it working. They are usually cheaper than a locker too which is a small added bonus. The only real downside is that it makes the car steer a bit heavier. For some that's a good thing since highway driving is improved a LOT. The car wants to track dead straight all the time.
