The Twin-Stick allows the use of two-wheel drive, low range, and a true neutral. With the factory shifter configuration, the neutral only disengages the transfer case from the transmission. It actually has the front and rear drivelines hooked together, so if you are towing using this, you are not wearing the transmission, but both the front and rear drivelines are spinning. The rear driveshaft can be removed for towing, however this still spins the gears in the rear axle.
The two-wheel drive low range is great for people with a front locker. As those of you setup with a front locker know, the locker keeps pulling you straight when you are trying to turn. With the Twin-Stick, just moving the 2/4 lever into two wheel drive disengages the front axle, and the locker is no longer pulling you straight. This makes tight turns much easier, while allowing the slow speed control of low range. By having two low, the front axle is relieved from undue stress, and four wheel drive can be re-engaged, even while moving, by just throwing one lever.
