where they are located, they have almost negligible effect on stall characteristics. They do alter cruise drag, and depending on the location, they could alter the cruise trim state slightly, but nothing much. The flight crew wouldn't see the difference on the instruments, the bean counters might note a slight increase in fuel costs over time. If that was on the leading edge of the wing, then all bets are off, but they are not. Aft of 0.1C, there is not much effect on the stall. darned ugly though.
