I am running both Novarossi S5 and RB 5 port. I was told to use, by a very experience boat racer to use the hottest plug possible so I always use Novarossi #5.
Always have good power from it, and just started using 40% nitro. Never short of power and haven't have any problem with the plug hot plug.
I tried once with a #6( med cold) plug, the temp drop 15% right away without any adjustment on the needles. ( using 30%)
After adjustment and the car seem to run well. But when I tried to restart, the plug broke then I decided to stick with #5.
I am sure there are advantage of using different plug, please share your expereinces guys.
