That's funny as I'm the same way. I try never to pay higher than the 'N' mileage rate (was forced to do 'NK' once).
Rene made a good point on his blog about this. Flights available with 'N' inventory usually have many seats open and perhaps not many elites. Hence why it seems so easy to clear upgrades on miles flights when 'N' is readily available. Food for thought!
