I always have on me two mini 450's and one 650 twist. If I remember I also throw a bigger backup (1100) into my purse.
Then I have a makeup bag with a bottle of juice, an ego charger and lots of half-empty carts and clearos that I also keep in the purse. And every night I refill the 2 most empty tanks from the bag.
Leaves me with lots of juice variety, lots of backup, and feeling somewhat comfortable that I won't run out of anything.
...I was also the girl who was never without cigarettes or a working lighter, so being over prepared is nothing new to me.
