With a bow like that shooting that fast, you could definitely go with a heavier arrow to get awesome momentum and kinetic energy and still have a flat shooting arrow.
I just switched from the Goldtip XT Hunters to the Goldtip Kinetics and they are heavier, but should hit hard and fly well and have great penetration.
Easton has great arrows in their Axis.
Carbon Express Maxima are awesome...and pricey.
But you'll want to consider as well if it will have a narrow diameter shaft, and potentially what inserts, if it will be a regular thread or a deep six, making it tougher to get some broadheads.
This is where you'll get a different answer from everyone out there. If you're looking for a good deal, dudes sell good sets with 8-10 perfect arrows for great prices, or you can pick up deals online from camofire.com and such.
Good luck
