You're welcome!  These are inflectionally interesting stems, and also
interesting because of the comparative factors.

Any idea how these are inflected in IO?

Also, I have to admit that I didn't look for pira (?phira) forms
elsewhere, though I'm pretty sure they don't exist in OP.

It occurs to me that r ~ th ~ dh (presumably the latter are *s/*z?) is not
a standard alternation in IO, so this looks like two different stems, one
with medial r and one with medial s/z (<theta>/<edh>).
