Depends, on whether the bow bends through the handle or has a stiff handle.
Bend through the handle I like an arrow pass 1" above centre. Its seems to be the best compromise. AP at the middle, hand takes up too much of the lower limb. AP 2" above the centre looks wrong to me.
For a stiff handled bow I prefer equal length limbs, AP 2" above centre. Alternatively a lower limb 1" shorter works well too.
