My thoughts on a deep sump pan is to use the same amount as before in order to lower the oil away from the crank and rods. Using more oil will extend the oil change interval a bit, and the oil takes longer to reach operating temp, but less windage losses and reducing air entrainment is the real benefit to me.
When you do your ring break in procedure, don't forget to slow down using engine braking as you cycle the engine through different speeds/loads. I avoid WOT runs for about 1000 miles, but other guys run them hard from the get-go and report no probs.
