This is going to get interesting....
I say for a beginner lady try a
Champion Sidewinder/Valkyrie at a lighter weight 166-169 grams (for drives off the tee, longer shots)
ESp Buzz/Cro/Panther at 170-175 grams (for mid range and approach)
Aviar P & A/Magnet for putter (170-175 grams)
Another option...but still might be a little too stable for ya at first... is a 150 class DX Destroyer. It would would eventually break-in into a fast long distance driver and might turn into a great turnover disc...once you gain some more power and beat it up a bit
