Though I have yet to build the 700 (as I am in Oz just finishing a work trip.....with my kit waiting for me for over a week now back in England....doh) I have just bought a 2S FP EvoliteV2 4250 here in Adelaide.
The web research I have done suggests that the 8717s are hungry servos and the pack needs to have some mAH to cope with a number of flights in a day.
Reviewing the AR7100R instructions also suggests something around 4000 for the 8717 setup so that's what I'll go with for piece of mind until I complete break in and get a feel for the mAH draw per flight for my type of flying.
Looking forward to getting stuck in with the build when I arrive back in the UK on Thursday morning!

I have 8717s (running on 6V) on my MA Stratus (90) and have been surprised that current draw is only around 250mAh per flight - using a EVO Lite 2100 and Align reg. On my T700 I have a 4 cell NiCd which also is drained ~250 per flight on Hitec 6975 servos so IMHO normal sized flight packs ~2000 mAh mark are gonna be good for 4-5 flights.

I'm running 2 x FP1800's using the 8V system. With the 2 FP1800's the 700 is nose heavy.
Here's a pic of the lipos:

Running 8717's and using the 1900mah 2s Align rx pack . It takes 1100mah on 3 flights, so 366 per flight. A bit more than my 600N, but not much more.
I could go to 4 flights and using 1465mah , just under the 80% rule.
I might be getting the Outrage 2500mah 2s which is almost the same weight, but I could get 5 flights per pack before recharging.
