I used the Duramax packing, same stuff as discussed in the pbase article. Shaft turns easily, no heat build up and no drips at rest. It is hard to tell what the flow rate is under power, a guess would be a drip every 2 - 5 minutes.
After a year I pulled the shaft ( easy to do on a 30 ). No wear or scoring. Shaft is polished where the packing sits but other than that nothing to mention.

I should have said, "... will drip once per minute..." (phew, metric still gets me sometimes :) And yeah, this guy does a great job of presenting boat chores information.
