Oddly, the noise of the federals went away above 80 so it's a resonance between 60 and 80. Was silent at highway speeds which is a relief...can actually go long distance without irritation.
On a wet but not raining road it held well, kicked out very slightly full throttle in second, but it was very predictable and no spin in 3rd. I'm happy with that for a dry tyre. Will try some twisties on the weekend to see what the sidewalls are all about.
