A bit of an update--instead of doing 60 MPH, I now do 55 uphill, DWL'ing to 50. Downhill... I'll just let it roll however fast it goes. I've got it up to 75 a few times... And I've replaced NICE-ON coasting with Fas on the longer declines (anything > 15 seconds). It's pushed my commutes into the low 50's if I can avoid too much traffic.
