Every truck I own gets a Detroit Locker in the rear period! The Detroit has descent street manners,reduces rotating weight and is strong than the stock L/S or Open.
No amount of rotating weight within a differential will begin to compare to the increase in rotating weight of larger tires or wheels.
Anyway, the TrueTrac is a Torsen type design, which is very streetable and works really well for traction. It's not ideal for offroading like a locker, but for those of us not climbing rocks and ruts it's a great choice.
