I would have to say the 12 bolt in your truck is the best choice. a 12 bolt rear end is about 30 lbs lighter than a 9 inch. a 12 bolt loses 3.5% less power than a 9 inch. that is based off the rotating mass, and the fact the pinion gear is offset lower than a 9 inch. a properly set up 12 bolt will handle any amount of streetable power. sure the removable center section of a 9 inch is nice and all especially for the drag racing crowd. that's just my opinion, this debate has raged on for years with no end in sight.
