What battery capacity for max flight time and servo combination should be used for this huge model with approx flying weight of 25lbs? I'm aware of how I choose to fly the model flight time will vary.

Most of todays cyclic servos will have plenty of torque for that model, ide say anything over 10kg/cm will work fine. Reliability is most important so pick servos from a well known manufacturer like Futaba or JR.

That model uses the standard 2x 6s 5000mah packs in series and should be good for 10 minute flights. If you are wanting more flight time you can use 6000mah packs if they will fit. Alternatively you can use 2x 5s 6000-8000mah packs, this does 2 things to help flight times 1. It naturally lowers the head speed. 2. You can carry more capacity (mAh) for the same size and weight.

60% of the time, it works every time!

Just make sure your SBEC/etc. can provide the proper current to power the hi-torque servos and all of your avionic systems.
