Varied opinion....

Unless you're shooting high level competition, you won't notice difference between .001 and .003 straightness arrows, and I think with that thought in mind, there are a variety of arrows you could use. I don't have my OT2 available, as I'm at work right now, but I believe that you should be shooting a 400spine arrow with a 100gr tip at 28" to be spined right (I'll double check in the a.m.) If you want to go with a SHORT 26-26.5 arrow I think you'd want a 125gr tip to balance out the spine a little better, and up your FOC to get a little better flight.

To me personally, the BEST arrow for the money I've found is the one in my signature which you would need a 55/70 series in. Fletch it how you like, but I'm not a big fan of getting stuff refletched too often if I don't have to, and BLAZERS, or another similar vane, would be on my arrows if I were to shoot a WB.
