Crosswind correction techniques

Hi,
 I am trying to understand the best way to correct for crosswind
during ground reference manuevers. The standard procedure as described
to me by my CFI appears to be to point my nose at an angle (or crab)
into the crosswind and thereby compensate for the crosswind. However I
recently came across another technique from a friend where you use
ailerons to roll slightly into the wind and use opposite rudder to
correct for the roll and maintain a straight line of flight. Is this a
valid technique? Please advise!
