The nice thing with the double case is that if you don't plan on hard wheeling all the time you can still have a stock low range, then when you need more kick in the other case. With the case gears you are always in real low range. I don't mind cause I go out to the harder trails more often. Even on light duty trails it doesn't bother me to much. Just put in 2 or 3 and have a desent low range and not to low. Just thinking out loud and some info for you.
Dizzy has the double case with stock gears and he loves it,
