Quite possibly. The main problem fiddling with the settings was the fixed line-length, which is why I ended up in landscape mode. This is presumably what K2pdfopt re-optimises (how good a job it does, you'll have to find out for yourself).
All of which reminds me why I avoided pdfs like the plague, when I moved to an eReader. What few I can't avoid I read on my (pivoted-to-portrait for the task) 23" monitor.
But, having gone through this reprocessing, it isn't clear what particular
advantage an HD 6" has over a non-HD 6" for pdfs, beyond the fact that it yields slightly clearer/more-readable any
text (regardless of whether its pdf, epub, lit or whatever).
