I completely agree with your analysis except for the Avon tires, which I found very good on the Rocket, even though, for the first time in my motorcycling life, I had to change them due to uneven wear on the front. Looking at the photo of Protonhound's Cruisetec, it confirms that, as I mentioned in another post, this wear is due to the motorcycle's design!
Regarding tire pressures, I've also lowered the manufacturer's recommendations, which are, in my opinion, completely ridiculous. I'm running 2.5 bar front and rear. I'm going to try going even lower like you, since summer is coming...
Note: I'd like to try the Bridgestone, but it's unavailable here...And what tire should I put on the front?
