I was always taught to run as warm a plug as you can without causing detonation. I have BR8ES's in both of my Blasters and they are still the original ones. If your Blaster runs fine with your BR9ES then stick with it, I think that the only difference is that it might be more prone to fouling (due to being a cooler plug). I know that when I lived in Texas many people liked to use a cooler plug in their dirtbikes because of the heat and humidity.
