I have ARB's front and rear. Had them installed in Feb. Great to have them fully selectable. I did considered Detroit True Track upfront and as Jason said, you can't beat the reliability of the Detroit locker for the rear.
I love my Select trak (NP242 transfer case) for the full time 4WD in the winters, and I don't think the TT would be very friendly with that combo, so the only choice for me was ARB's all around.
