You may have trouble getting the spine low enough in carbon to shoot well out of such a light bow without loading the front of the arrow so much that they are 800grains.
If you want something economical, I'd go for something light weight like Beman ICS or similar easton shafts in 600 spine. keep them full length and you just might get the spine low enough.
Or even consider using wood shafts. You can get lower spines, they will probably be heavier but what can you do. Woods are tougher than you think. I find that its rocks not stumps that break my doug fir arrows, and I'm shooting out of 40-50# bows.
If you wanna spend more money, victory makes carbon shafts in .600, .700, .800, .900 spine etc. they're like $150 /dz for the VAP though ...
