help for coil on tripple 18650 pwm mod

[mastervapes8489]

So I have a Tripple 18650 pwm box mod coming in, I'm curious on what build to put in it, ik I need a high ohm build... I have a steamcrave Titan coming within the next week with a series deck but I need a coil for my rda.. I have 24g a1 kanthal what build could I do with high enough ohms to be Super safe.. also what are my limits?
I'll be building on a bonza rda or a riot rda
Thanks in advance everyone
