i dont know if the rest of you noticed this or not. for me, the 'correct' amount of ailerons would be just sufficient to offset the rudder input! i.e. if you have the correct amount of ailerons, you should require minimal rudder input!? at least that works for me.
and if you DO NOT hold the ailerons till airborne, your wings are bound to 'dip' just at liftoff. i guess, these will be more significant on the larger boeings.
