I'm curious – why the 2.35 upfront and not a 2.1?
Largely because you want the larger volume tyre on the front as this is the one doing the steering and control. Kona were the first to do this on their production bikes back in the day; the Joe Murray tyres were always 2.1 front and 1.85 rear, or thereabouts.
Whether you want Dual or single ply depends on how fast and heavy you are. I couldn't get away with a single ply on the back in the Peak; i'd pinch flat all day long. However if you run them tubeless, then a single ply will be fine.
Forget super tackys or the even stickier slow reezay; you'll drag like a queen in Brighton with them.
The Minnions DHF for both front and rear will have less rolling resistance than the High Rollers but they will break traction slightly quicker in the turns, especially on loamy soil (of which there is almost none in the peak!).
