I would try the Easton Storm 500's. They are usually around $60/dozen (fletched w/ Blazers), and a great starter arrow but not very strait for flying broadheads...Come hunting season you could bump her up to the Beman Bowhunters 500 ($85 w/ Blazers) or Beman Hunters 500 ($100/dozen) (same as the Bowhunters, just a little straiter for better broadhead flight).The Bowhunters fly very similar to the Storms and you would need very little adjustments between the two shafts. I have had very few issues with mine, and they are not too heavy so I get fairly strait arrow flight (I can only pull 44 lbs, so a heavy arrow really arches even at 30 yds), but yet heavy enough to get good penatration.
Easton also make the Ion arrows ($105/dz fletched w/ blazers) that are designed for light weight poundage and shorter draws.
