It's always been a struggle finding carbon arrows that are spined light enough to perform out of 30lbs bows. My wife and daughter have been shooting Jazz 1716 shafts but 3d shoots and shooting at a soccer ball around the yard takes toll on them and most often I'm having to straighten them after each outing.
After some searches here on the pow wow I stopped by the local archery shop and picked up a few Carbon Express Predator II 800's. Wow! What a great arrow. They come with an outsert which I personally found top quality, providing the ability to change tip weights. The 800's fly perfect out of both my wife's and daughters 30lb Bear bows. Neither one of these bows are center shot, so the lighter spined 800's are definitely the ticket! They also make a 700 which is the next step up in spine and would probably have been our choice if their bows where cut past center.
It's so nice to be able to find quality arrows that are also durable!
