I have used the PHD2 drift align in the past, but have shifted to using the EKOS polar alignment. It is generally much quicker to use, mostly automated (some issues with captures starting before the mount is stopped - use manual mode), and is accurate. Note that PHD2 recommends that polar alignment should be slightly off to avoid DEC oscillation (not sure what the recommended amount of misalignment is - my CEM60 is about 1.5 arc-minutes off according to PHD2). Overall, it works very well - much preferred over drift alignment. See PHD2 best practices for details.

If you still want to use drift alignment, use EKOS to align first, and then try PHD2 drift - you'll find your mount will be very close, and it will be much quicker.
