So why is it not the reverse? If the shutter is open for longer on a smaller scope isn't that more time in which a problem can exhibit itself?
What sort of aligning/guiding issues have you had to struggle with? By that I mean - was it a matter of practicing a skill until you mastered it (something I have more confidence with) or is it more a matter of playing engineer and chasing your tail to diagnose and eliminate all the possible causes of a fault that can only really be diagnosed by swapping parts out one by one (I used to do this sort of thing for a job and found it really frustrating).

Yup, you are starting to get the picture. Hence accuracy and solidarity in the equipment and alignment. Flexure in optical systems, dirt, dust, wear, all these wonderful things keep us thinking and solving problems as we search for the perfect solution. Which of course is unattainable. So we keep trying. And throwing $$$ at it.
We're all nuts in here I tell you, welcome to the madhouse !!
My alignment issues were with my mount stability, now solved, flexure, difference in accuracy of my guide scope system and the imaging OTA. Some PC problems and trying to do some things a bit too much on the cheap. eg PC webcams instead of proper astro cameras.
Frustrating yes, challenging is how I see it. Keeps my brain functioning at full speed. I get much of my astro pleasure from the build and problem solving to improve, make new, find alternative solutions. I used to do this sort of thing for a job too, some days were better than others but I've always been an engineer and a tinkerer\DIY nutter.
You'll hear heaps of similar stories on here from others.
