I try to even it out so there's equal amount on either top and bottom end of the plate.
With me, my plate sits evenly over my Center-of-Gravity. So I try to sit my wing as such too.
My wing has 3 holes.
On a Dive Right plate, it's Center Holes. On my Paladin plate, it's the top wing holes.
It all depends on your gear positioning, which is why some mfg's give more wing mounting holes and plate center holes.
Short people using a normal plate would probably have to shift the wing down to avoid the bulk of the wing being inflated above the back of their head for example.
Since it doesn't make a difference for you, string it up to which way makes you look less lopsided.
