Replying to Girls All Mountain Ski

Was wondering if I could get some help about some girls skis for my girlfriend. She needs an all mountain do it all sorta sk,i for a season in Canada. She is about 5,6 115lbs and a beginner in terms of NS level skills :P . Were from the UK so luckily can get hold of some older models to save money although I dont know a lot about girls skis or generally what size she should have.

Here is a shortlist that I can get hold of whilst saving a bit of money.

Line Afterbang 166 - Not enough all mountain?
Line Anthem 171 (various years) - is 171 too big lines ski kinda short or is 161 better?
Line Celebrity 172 or 158 (various years) - seems like a really good ski but the 166 is full price
07/08 Line Shadow 167  - Again not enough all mountain maybe?
07/08 Amplid Township 162 -  Too short? Not enough all mountain?
Armada ARW 161 (07/08) or 166 (06/07) - Is the 161 too short and is there any differnce between the years build quality etc ( its armarda im guessing not )
06/07 K2 Fujatives 169 - K2 run pretty long is 169 too big
08/09 Kung Fujas 169 - same as above
K2 Silencers/Missconducts 159 - Not enough all mountain - pretty crappy skis from what Iv heard
06/07 K2 Nancy 169 - Sounds good but again possibly too big
09/10 Atomic She Devils 164 - Sounds good but only 81 in the waist
07/08 Rossi Scratch Girl BC 160 - Too short?
07/08 Rossi Scratch BC 171 - Too wide and long?

I know a lot of nooby questions but would be great to get some help especially from girls who have perhaps skied these skis. 5ft 6 is about 167cm but being a beginner she could go shorter from what im guessing and being lighter. Also is low 80s too little for all mountain for a girl being lighter etc?

Personally i think the better options are:

Anthem
Celebrity
ARW
Nancy
She Devil
Scratch Girl BC

Dusnt really narrow it down I know but I put the others in just in case, any info on any of the skis above would be really helpfull. Thanks. Peace
