Hmmm, ARV's keep changing their flex every year it seems, not sure if they're noodly or stiffer this season, but they used to be really soft. People loved how they could ride the whole mountain as well.
Lizzies are really soft too, and probably about right for your height. They're pretty fat for their length, but everyone loves how they ride everywhere.
Those 2 pop up first in my mind... Keep in mind I haven't ridden either, I've just noticed many reviews and opinions, and scrutinized them in shops.
