Just to add to the confusion Graham, have you considered Marathon Mondials? I have 700x35 on my Tour de Fer and they seem a good compromise.
I have WTB Resolute 700x42 tubeless on my gravel bike, but I couldn't tell you anything about them other than my mate said "buy those" and he put them on for me! Certainly better than the tyres the bike came with and the extra width gives me some grip off road, which I need on the forest tracks as even with these I spin on loose gravel going up hills.
Don't roll with a pig in poo. You get covered in poo and the pig likes it.

I was a bit of an oddball until I was abducted by aliens; but I'm perfectly OK now!
