The thing with fins is it depends on your leg strength. I used Avanti Excels until I couldn't get any more speed from them because my legs had become stronger. So I switched to leaders.

Quattros are a heavier fin and requires a lot of strength if you want to get the most from them. I don't think there's a set of ideal fins for women, it just depends on your strength and what you want from them.

Alas would be a good all round fin if you can get a hold of them.
