To be perfectly honest i hate the K2 Cinch i had them and thought they were uncomfortable and poorly made, now they were 2010/2011 models so maybe they have changed. I seriously think if you are going to get easy step in bindings get some flows. I am both taller and heavier than you and i ride a gnu riders choice 166W. I have paired it with some rome targas which i cannot talk up highly enough, they are amazingly comfortable and super adjustable with pretty much anything you want you can do to the bindings.
I have owned a skunk ape and it was good although mine was BX no C2BTX (i like c2) which is why i have a riders choice now. If you wear size 14 show then try some shrinkage tech boots or some vans (they run smaller in my experience, i wear a 13 vans but 14 shoes). The burton bullet 164 has a waist of 262mm, in my opinion thats probably on the narrow side for you, you really want to be in the upper 260's even 270's if possible. i know its only half a cm but it may make a difference, im sure someone who knows more may chip in.
Im sure you can find something better than the bullet for around the same price
my names's Petey and i have gigantic balls
