My son's girl friend wants to start shooting archery with him and I'm giving her an old Indian Warrior 30@28 I need to find arrows/shafts any suggestionson spine? I want to keep it simple 100 grn field tips.

5/16 dowels work ok just check for bad grain run out with some sorting you can find some decent ones.

I use ICS junior's for my wifes bow with 100gr tips.

I second the 5/16 dowels. I use them for my daughter she was shooting 30 and now 35. I cut the dowels in half getting two arrows per dowel for her 22.5 inch draw. Could not tell you the spine they are too short but they fly like darts.

1816 Aluminum

I believe Carbon Express still makes the Predator II in .700 and .800 spine.

I like 1716s out of my 33# longbow.With 100 gr tips they fly great full length. On the lighter 30# bow, and especially if you shorten them, you might have to go to 125 or even 145 gr tips.
