I ran the exotek locker and pulled it after one practice day. The truck pushed into the turns and front tires balloned alot under wot with 5000 in both diffs. I don't recommend it for indoor. I put the locker in my basher and same thing the front ballons alot and steering is real agressive under wot. You have to run a tighter slipper with the locker for bashing for a more full time 4wd feeling. From what I read the center diff basically performs the same way. In the end the vts offers the best of both worlds. Imo, this is what I experianced.
