When I read subjects like this I realise that there might be all sorts of ways to deviate from the 'central way' of doing things. A tent is a tent and a tarp is a Tarp and never the twain shall meet for some people. When discussing options and variations it can start to sound a bit like the term Brexit is Brexit!
It raises questions in my mind about the best way, for example of how to keep dry, how to sleep and how to keep clean. We could all follow the 'central way', for example, traditional mattress and sleeping bag, or waterproof jacket and leggings or just using showers on a site.
There are other ways to look at the subject areas, mattress and quilt, poncho and rain skirt, carrying your own shower with you instantly springs to mind.
Sometimers it makes my brain hurt trying to get to personal perfection.
