Newspaper with Cloudflare & Rocket Cache (& Siteground )

I know this is one the theme won’t want to reply to formally, as the official line is WP Supercache, but none the less I expect a good few Newspaper users prefer Rocket.
I wondered if anybody would like to enter into a dialogue about optimum configuration of Rocket and/or Cloudflare with Newspaper?
As in what works and what breaks.
I have tried with Supercache, but for non techs it is a bit clunky, added to which the newspaper documentation isn’t up to date as to recommended settings anyway (they are aware of that and have said they will be updating it).
But for me I prefer the Rocket interface and documentation hugely. Plus in my situation it integrates with Siteground’s own server ‘Supercache’ (settings and clearing applied to one apply to the other), and it also has a Cloudflare connection.
I have this set up running like Usain Bolt on my other websites, but I am struggling with Newspaper so probably haven’t got things set up quite right for Newspaper’s needs yet. It is particularly slow in the backend.
Perhaps some other users with similar issues will come across this post and we can try to help each other out. If you are reading this more than a few weeks after I posted it, I’ll hopefully have it sussed and can pass on the knowledge.
