After you have reached a certain point of gear (since you have sow you have reached this point), the standard-conserve-rotation is: FO, 4xAB, AM or ABar(if AM has not procced). If your gear is not good enough to stay over 90% Mana (without any Int-procs, take a look at mage manabar) you have to switch between 4xAB, AM and 3xAB, AM.
85% is too low unless you had to burn an add or something. In this case switch your rotation to 2xAB, AM (FO is extremely usefull to get AM-procs)in order to get over 90% again.
