I got my gf a 136 dx leopard, 150ish diamond, 150 teebird, 160ish dx skeeter, 165 d stratus, and an APX (mostly based off of what I had laying around) She has the most luck with the diamond, and she can get some good d out of the leopard. We played our first round mostly with the skeeter, but she had the most fun when she started throwing the drivers and getting some nice d.
If you're helping her learn, this is what worked for me: make sure the focus is on fun whether or not you count strokes, keep having fun. I am learing to throw with my left (off) hand as she's learning right. I can face her and demonstrate the same motion. She can occasionally out drive me, and beat me by 4 strokes the last time we played, and I'm learning a skill that will be helpful on the course someday.
