Pirelli cinturato M is very similar to vittoria mezcal... seems this kind of pattern a good balance. It’s never going to be as grippy as a knobbly mtb tyre but has decent bite for climbing/braking/cornering off road but still rolls well on tarmac/hard pack.
It’s all a sliding scale of compromise eh.
The shallow spaced knobs on the g one bite, I just don’t think that tread pattern stands a chance on UK muddle.
I wonder if a schwable smart Sam could be a good shout, not sure if they a decent casing in narrower sizes though.
