Oh boy, now that'll be a volcano of a thread.
I'm actually okay with the concept of this thread (using the terms "woman" and "girls" in terms of style, rather than just age), but if you put it like that... well, just goes to show how different values are between the genders.
I think that in skating, there actually a valid difference between genders to consider because very young boys don't generally compete as seniors, whereas significantly younger girls (age fifteen or so) do. With males there's no special advantage for jumps in having an immature body: the strength that comes with age benefits them without any trade-offs. With female skaters, on the other hand, some young, physically immature girls have an advantage in terms of jumping ability, so if they can, they compete as early as possible.
