The Detroit Locker is going to be the best, providing you change the springs to accommodate what your doing and for the type of tires (slicks or treaded). For treaded tires, a #48 spring is what you'll want. Yes, it is a little noisy, but the abrupt lock and unlock is usually do to the unit having too high a spring rate, and once setup with the correct springs, you'll have a hard time finding a unit that can put the power down better with more predictability.
