Do you mean the bracketed series before combination? There's no problem here,
the HDRs I'm getting are very sharp.

Yup, am doing. I scale down to the smaller one, but it's usually only different
by a dozen pixels or so. I make the mask by painting on a layer over the
rotated image to wipe out the unwanted areas, then clearing the lower layer to
black, merging and blurring.

I never thought of that. However, my shadow can be anywhere, and my tripod head
gets in the way quite a bit.

Hmm, I've been unwrapping to angular and rotating at the same time, as per the
tutorial. Do you think keeping it in the mirrorball projection would be better
for matching and blending? Or do you really mean angular ;-) ?
I'm using megapov, so I figured using the angular map would be fine for the time
being. I'll probably supply both projections when I get a collection going.

I'll try post an example of the problem later today... it's slight, but enough
of a mismatch to be annoying. If it's an interior environment, straight lines
of walls/windows etc end up broken. Maybe I'm too much of a perfectionist!
