I think more Nitro also comes with less oil, cmiiw. Less oil means less lubrication and generates more heat and of course more engine part's wear.
Some guys have them tested, and the result is 25% is the max nitro you can have here in our part of the world for a .12 engine. My opinion, maybe 20% is the best percentage...
