are there any tests or other solid information about the qualities of HD vs

Then, the Pentax Forums review is linked to in the original post. This
is the specific section we're interested in:

thanks, i guess i was wondering about the coating in the abstract - what makes
it better? some of the difference in those tests seems due to the curved
blades, but internal reflections and contrast seem to represent the coatings,
however it also seems to vary a lot per lens design
i have the 15mm SMC, and the only other Limited prime i'm strongly interested
in is the 35; from those shots, HD on a 35 gains a smaller hotspot at the
expense of fuzzy startbursts; bokeh doesn't seem to benefit at all from the
curved blades; what would be most helpful for me would be a daylight "contrast
test" on the 35, like that on the 70, on both a normal scene and a macro shot
