Since the pistol has a soft tip you CAN mount forward with worrying about major nose dive in pow. sorry had a little typo there.
Check out the public enemy mounting thread in ski gabber. its based off a 179 pe, but i imagine it fairly similar for the pistol too.
i still say +5 if you want to do a fair amount of park, and ski switch like a gangsta. my buddy has his at +3 and he said he wished he went even a little more forward.
