for me its kinda like mudhunny said, I like to lean the bike and stay centered over the BB. That is what comes natural to me and I have always done that even in the bmx days.. but it also depends on the clearance I have on the sides (trees).. I used to be able to lean the bike at a 45 degree angle bmx that is, mtb not as much but I try. Also something that I learned when cornering is to stiff arm the arm that is on the inside of the turn. It might seem funny at first but it definetly works (especially in the sandy stuff atleast for me)…
