We just did a 4 day dual sport ride and it included quite a bit of steep rocky climbs and descents and I just left the ABS on the whole weekend. Never had a single scary moment of "run away" caused by the ABS cycling. Some of the steep sections were loose, rocky and you were constantly being bounced off your line etc. but no problems with the ABS. I have to admit a few times heading over a crest and looking at the rocky steep slope I was about to head down and thinking about the ABS. They just worked.
Mine just stays on.
