based on the fact that you are a male, and not racing FIS, there are 2 points to consider....
1. the sidecut does not matter! you are free skiing on race skis you can turn where you want and when you want. so, for free skiing the difference between a 23 meter ski and a 27 meter ski is not that big of a deal. from a versatility stand point, you would find that the 23 meter ski versus the 27 meter ski would be easier to work around tighter trails or where there are more skiers on the mountain.
2. as far as the hook-up factor, do not believe everything that you read or are told about sidecut. a women's FIS ski has to be greater than a 23 meter radius, to get that dimension there are only so many combinations of tip width, waist width and tail width that get you there. a race ski is much more than the single parameter of the sidecut dimensions. if the tip width made the most difference, then there would be a one to one relationship between the the fattest tips and the most world cup podiums. that is not the case. flex, sidecut, profile, taper angle, materials, plate & binding all have influence on the overall feel and performance of a race ski.
the choices that you have mentioned are all great skis. try to compare apples to apples in terms of womens FIS GS skis range from 175cm to 184cm with 23 or greater radius. there are many great skis currently available if you prefer volkl go with it.
there is another option to consider that may be more versatile and that is some of the masters "cheater skis" . they are built like the race models, but have slightly tighter sidecut radius, usually in the 18 to 21 meter radius.
