In that case I respectfully suggest it simply doesn't matter, either at all or not enough to bother debating.With stringing 2 strings STB and the other 2 top load than flipping them over, you are already mixing variables and adding to inconsistency of the results due to all 4 strings being of different gauge. How would you expect to feel any difference each time? String up G and E strings for me via STB and top load at the same time, than flip than over after a bit of playing...I wouldn't be able to decide the difference due to the mixed variables.
