With a lower poundage bow like that I think she would be better off shooting a fixed blade head. Why spend KE on opening a head when it could be spent on penetration?
I agree with txjourneyman.
You also might be able to get a hold of one of these computer programs, such as OnTarget and enter all the different variables and it will give you a fairly accurate estimate of KE, speed, and a whole bunch of other stats. I believe that the OnTarget has a 30 day full version trial for free. I don't have the program, but have used the trial version and it is a really nice tool to have. I know several members on huntingnet probably wouldn't mind running the numbers for you
