On3p mango 90 or 100?

hi everyone, i hope you are not sick of all these threads lol.

i’m 6’ 160lbs and will be riding whistler blackcomb 85% park.

I am pretty decided on the on3p mango but unsure if i should get the 90 or the 100

would the 90 at 186 length would be better?

the 100 at 181?

would the 100 at 186 would be too heavy?

mounting wise should i just follow the recommendation like every other skis i had
(mostly armada)
i’m leaving you alone with this shit after tbis one, thanks for your help!💗
