Using Easton's chart I came up with XX75 1913 or a lighter arrow in carbon wold be the Redline 690. I wold think the Redline would give you a little more varience if she goes up in weight some. These figures are based on a 25" arrow. You didn't give her drawlength so it makes it a little harder to figure. Really, you should give the length of arrow she shoots to have a more accurate figure.
