Great points!!! I love it now. I recall it being a bit more harsh over small stuff like expansion joints, potholes or gaps in pavement sections, which I chalk up to the stock tires likely having much softer sidewalls. But the bigger difference was that it was more "bouncy" over larger dips and bumps. But I'm now either used to it or just like it. On the whole, the ride quality is NOT a reason to not have this setup.
Now, that said, I'm going outside right now and airing down a few lbs as you've suggested.
