Now, I think, from the first screenshot, the top two are the top mounted ones, the second two on the side and the last is the underside one. So how can I tell from the reload screen (shot 2) which one is running the lowest that needs a reload? Is the "order" the same, as it were, so the last one corresponds to the underside MC?
Sorry CMDR, I have no idea!
This evening I have mostly been taking my 'Open Only' CMDR out in the mining Adder (with its measley 16ton cargo hold) to hoover up some Void Opals, see how it is now.
I got lucky, first VO 'rois I found was a mother 'roid, at least my tiny ship, so I was full up in about 40 mins (normally takes me twice that - finding the 'roids is what takes the time, I think I am sharing 'my' area with some cross-platform folks - there is regular activity evident - traffic reports, state changes etc. - but I never see anyone around).
This is an Adder, honest:

Not the greatest image - its a dark coloured ship in a foggy environment. Enhancing and tweaking the image only brought out a nominal amount of detail.
But it is an Adder, wearing a ship kit!
Then I spent the next couple of hours trundling around looking for a market. Started with the usual 3rd party tool ('mining tools') which was a bum steer, kind of what I expected, from what I've read.
So then I broke out EDDB and started looking for Refinery economies (I hadn't visited nearly enough local systems for the in game tools to be useful), see which where most up to date demand wis.
Best I found where several places offering about 25% the previous price. Not much return (about 2.5 McR) for time spent, but I felt like was engaging with the game more than when I just hoover up a load of VO's and just jump to wherever the tools tell me to go.
I'm still not likely to take up mining as a career, but I had a low key fun time trying to tackle the 'puzzle' of where to sell my VO's.
