Smoking - Logo Refresh

After choosing to use the red x as a symbol to represent this whole thing, I had another look at the logo I ended up producing for Kick Butts, Take Names, and have decided to change it.

First I tried just changing the red to the same red as the colour of the x is, but I still think I need to just change it completely.

I've decided to try just having the X as part of the logo.

Out of these logos that I have now done, the two that I prefer are:

I look at one and pick that, then look at the other and pick that. I will leave it and come back to see which one I am draw towards first.
