Locker or Limited Slip?

[mclairmo]

Anyone got a locker of any kind or limited slip in their rear diff on a 2wd? I want to install one (or have one installed) but don't know what is best for mostly street driving but occasional desert/dirt and towing use. I don't really want a lot of shakes and shimmys like a Detroit Locker but not sure if a limited slip is strong enough and will last a long time. Also, not sure if an air locker or electric locker is best since they would cost more. I have a Lock-Right in my big block Camaro and while it really locks the diff on the straights it also gives me a loose feeling in the rear sometimes and clicks loudly in the turns. Any thoughts?
