Yes Phil-E, I've suddenly got interested in that Hancock Kinergy 4S2, following this week's Autoexpress magazine, where it came top out of 8 all-weather tyres. It wasn't included in this year's 'Tyre Reviews' AW test but did well, coming 2nd in their 2020 AW review, summarized there as a hugely impressive tyre with no real weakness. My particularly emphasis is for noise & ride which you comment on favourably & the tyre did very well for ride in the 2020 review, but noise was average. However this week's Autoexpress notes that the tyre has been developing all the time and it was now the quietest on smooth tarmac - rather better than the Goodyear Vector Gen3 whereas in 2020 'twas the other way round. However noise on rough surfaces, sharp ridges etc., a much more annoying noise aspect for me, wasn't commented on by Autoexpress - let's face it, most tyres are pretty quiet on smooth tarmac, including my current Turanzas.

Other apects from an average snow rating in 2020, Autoexpress reckon it's developed into a really good tyre for snow. It was always good in the wet, probably the most important safety aspect for me down here in the SE and is the best for aquaplaning. Dry weather performance remains average, but I don't go racing around these days. Rolling resistance is not that good, leading to 3% worse fuel economy than the best Pirelli, but hardly a significant cost penalty. Wear is probably not a strong point either. It's been off my radar up to now, but all-in-all it could now be top choice for my next set of tyres.
Strangely the Autoexpress review this week didn't include the new new Michelin X Climate 2.
