i was wrong,i was on a muddy track coming home today
selecting low-box engages the centre DL but didn't cancell the abs
it cancells only when you engage the rear DL as well
when coming down steep slippy unknown tracks, i'm still not sure if i'd prefer abs or not
we're having a bit of rain at the mo',i'll try it and see tomorrow on a track i know
must admit i like the extra feel and power you get without abs
