would you say

that:
none works best in sweaty areas close to the body
nol works best in \"clean\" areas, e.g. wrists
this

sounds good, as we don;t want the nol to change into none for better control

rone...who knows?

then again PI

is reported to work well behind the ears...
wagg is meant to be good behind the neck

also hair is good for the

high surface area...eyeborws and sideburns?

what do you think
