Do you pre-fill your oil filter and, if so, are we doing it right?

[aussiblue]

BTW I have always pre-filled and in the last 20 years or so always from the center outlet hole. However, I know when I started out I used to fill from the perimeter holes perhaps because vertically mounted hole down filters were more common in the 60's and 70's and it was probably often the only way to keep the oil in the filter; but then you had to make sure you bought one with an anti-drain valve as not all had them back then (I think they were less common in fact). I probably moved to filling from the centre outlet holes when I stopped servicing vertically down mounted filters (my mates Rambler Rebel sticks in my mind) and started changing filters on cars where the filter was always vertically mounted hole up or at least angled up where the spill out of the outlet hole was no longer an issue.
