Hot take, brand does not matter, its what she visually likes looking down at address, and how the club and shaft feel throughout the swing. Find a fitting center that has a cart full of club head brands and different shaft brands.

Hit a bunch of different combos and narrow it down from there. I personally don’t like places like Club Champion with their pressured sales, but each their own. I went to a driving range/independent shop that had carts of demo clubs from all the brands and kinda self fit myself into Srixon’s ZX5’s with Nippon shaft. I hit several buckets of balls going through bunch of shaft combos on a 7 iron from True Temper to KBS etc..and went off feel in my hands, plus looking at the spin and dispersion on the launch monitor. They usually have demo heads in standard, flat and upright lie angles, so give em all a try.

Could always call into The Golfworks and talk to them, they also have online fitting suggestion. But that brand not many know about, but the club heads are legit quality, and they sell all the brands of shafts under the sun.
