Howard - You got a very nice crumb. The crust looks nice and crispy as well. I might suggest that for your cooking setup, add 2% oil, 1% sugar, and at least 1.7% salt. These additions will help with browning and actually cut down on the time in the oven at 550. You will also notice a difference in flavor.
If you do not add these ingredients for health reasons, I still think you made an excellent pie.
