I was only thinking that the lower the RON the more likely Detonation or pre-ignition is, you may need to "de-tune" it a bit thus making it less fun when you do want to go for a burn. Taking a small step back can feel like a country mile when you're really used to something.
Seriously though, hat's off to you for doing it, you obviously really enjoy the car and want to find a way to use it all the time. It's not a route I'd consider but it doesn't mean I don't respect what you're doing. I didn't mean to come across like I was having a dig.
