You can actually calculate the wrapper versus filler effect mathematically, and as the percentage of wrapper drops with larger ring gauges, so does the intensity of flavor. That's why Lanceros seem more intense and also why I avoid ring gauges beyond 54.
I'm smoking a Tatuaje Fausto now that probably has so much black pepper flavor that it probably doesn't matter, and I'm loving it. As you increase the ring size, what you get is more air and more dilution of flavor. For the guys who want milder smokes, big ring gauges are fine, and that is why they are all the rage now. Me, I like it as strong as I can get it.
The Fausto is wonderful!
