Wye vs. Delta

I was talking about timing. My post says that a wye works better in one direction then the other(a result of 'timing'). (the only advantage of delta is that it works equally well in both directions)
So.... will reversing direction (by changing 2 wires) also reverse the timing, and how do you tell which is the good direction and which is the bad direction. And further, if your ESC wont let you reverse your throttle setting how (or can you) reverse the timing if its set for the wrong direction?
Anybody getting any of this???

Timing, with sensorless motors, is maintained by back-EMF (timing) pulses through the three motor wires. Thus, if the motor is operated in reverse, the controller recieves the back-EMF pulses in reverse order as well. Timing isn't affected in either direction, so performance should remain constant in both directions as well, no matter which wind you have in the can.

I can't see there being a performance hit, or anything running a brushless motor in reverse. (or even really being a reverse...)

Are these controllers sensing the sine wave naturally generated by the motor, or kick back from switching pulses? I would think it would be easier for a controller to sense motor position by the sine wave method. IMO
