It really depends what sort of delivery you're looking for.
If you want an inswinging corner (ie a delivery that is angled towards the goal), put a left-footer on the right, or vice versa. For an outswinging corner (ie if you're looking to hang one in the box for players running from deep) - put your left footer on the left (or right footer on the right).
I suspect all of this is totally academic as far as Top Eleven is concerned.
All I can add is that like Ryan above, my right-footed (DR) free kick specialist appears to have little problem scoring from either side.
