Well, if you read my *long* post from a week or so ago, you'll know
that motor mismatch makes up at least 11% of performance, motor
direction perhaps 1% or at most 2%, and HOW YOU BUILD YOUR MODEL
accounts for at least 7% ... even when you are being careful not
to trap axles.
Compared to those things, motor direction is almost irrelevent - and
certainly not worth much extra complexity.
