If the fluid has a lower wet boiling point, the heat can generate a boil in the fluid that can be compressed which lets the lever go limp just when you're getting a good feel for your input. When it cools down, you don't have the problem. Additionally, brake backing plates can warp either permanently or temporarily because of heat. I'm not a fan of the EBC's. I just haven't had a lot of long term, consistency from them over years of doing this. DP, Galfer, Vesrah, and others are often a better opportunity. I do know some that like them and have good luck.
Maybe that will give you some ideas.
Fluid wise, I've used the Motul products, and I am currently using the $$ Castrol SRF in some of my bikes.
