After transferring heads, don't transferring adaptives take care of that, or do you not transfer adaptives as a matter of routine after head swaps?

Seagate has the option to transfer adaptives. With Western Digital, it has always been to do an average of the microjogs...which is tough when the original ROM is all zeros for the microjogs to start with. This is the first time I've tried the DAC values and must say that I'm quite happy with the result.
