I know this thread is a bit old but I just saw it.   
 
I use two 1.0mm nozzles with my HFS-5 kit and spray 100% meth.  I had the thought that when you spray that large a quantity of fluid, even if eater is better at cooling then meth, it doesn't matter anyway.  There is so much meth being sprayed that I think it cools it enough, and I would rather gain the benefits of the octane of meth.
