I'm very pleased with the NANO system. Although i've won 7 hi points championships over the past 5+ years, I needed something more for a few tracks that have bad water, and usually bad air. I stayed away from n2o for several years because, as a bracket racer, consistency is so important. However, with the NANO system, I've found that i can dial it in as close as i need to, with the stability to maintain the same level of performance throughout a weekend.
