Ya definitely need to mess around with a field point test kit and find out what she likes. I have a Martin L-100 longbow (50#) that likes 200 up front, my Kodiak Magnum recurve (also 50#) likes 300, and my custom hybrid likes 250 (49#). The great thing about the carbon arrows is that once you get it figured out what it likes, you have a LOT of options on how to get that weight. I make up 200 gn broadheads with 125-135 gn heads & 75 gn steel adapters and have different arrows for each bow. The recurve arrows have 100 gn inserts, the hybrid 50 gns, and the longbow has the aluminum 11.5 gn inserts. Hope that helps.
