That's good news on the switch and it is what I hoped would happen. The jam

Macrophotography is good fun but has its challenges as you are finding out.
May I suggest a couple of things?

Please do - I'm appreciate the benefit of other people's experience

1) Using the smallest aperture makes sense for depth of field but lenses
usually perform best when stopped down only 2-3 stops from fully open. For
example, when I use aperture priority with my 15-85mm f3.5-5.6 lens I'll
probably use f6.3-8.
2) You may find it easier to take photos if you use only one extension
tube despite the resulting image not being as large.
More tubes = dimmer viewfinder.
Try using all three tubes then try using one tube. Load the images onto your
computer and compare the images after zooming so they are the same size and
see what differences you can see.

Interesting. I'll try this out. Thanks for the suggestion.

I used this technique when deciding whether to buy a 150-500mm lens or keep
my 70-300mm lens. When I used these lenses at the long end (500mm and 300mm
respectively) and zoomed into the images so they were the same size I found
that the images from the 70-300mm were sharper and had better contrast than
those from the 150-500mm lens. The tests saved me from buying the bulky and
heavy 150-500mm lens.
I have a 60mm macro lens (approx 96mm on my APS-C DSLR) which I use for
macro work in my garden (flowers and insects). I don't take it on holiday so
use my 15-85mm for macro work and the results are not at all bad. The 60mm
lens is a luxury and one I would not have bought at new price. I bought it
second-hand from a dealer I can trust (LCE in Nottingham and Derby).

I could be tempted to buy a macro lens but only if I'm sure I'd actually
get a reasonable amount of use from it.
