When I had the same dilema, I decided to bite the bullet, spend the money and get the ARB's front and rear. They are invisible while on the street, and lock up 100% when needed at the flick of a switch. Of course, you need to spend the extra money on the compressor, which makes them expensive (they are the most expensive lockers by themselves without the compressor already), but I feel they also ae the best. Plus, any problems with the air lines, you just cut them with a knife and splice them with quick connectors (takes all of 30 seconds).
