hey lucy knuckles ;)
Those ratings I think are specific to atom wheels and seem to vary depending on brands (so 93 in atom might not be as hard/soft as radars).
I know its hard to figure out cause there are so many factors: hardness, width, floors, weight...colour!
I just got atoms and am finding them to be a much better wheel than the radar tuners I had originally. But I was lucky to try some out first after reading n-forums about the subject.
I would try to narrow it down to a few wheels that you think would suit, see if anyone is using them and pester them about it.
I know that fugitive seem to be really popular with alot of the girls too so might be easier to ask someone to let you have a go.

I ended up going with the same setup as wonton and terror as i have a similar build to them and they seemed really pleased with them so poisons and stingers for me too :)
I also just got new bones reds bearings which are affordable and my wheels are spinnin like crazy! I have no spacers, I think the need for them may vary on the wheel (skateboard wheels seem to normally need them). But I am really not sure on that one.
Anywhoo, I am sure you must of already read the thread on our forum about this, I seem to go back to it often:
