A conference has accepted my two abstracts in the same track, the first for an oral presentation and the second as a poster.
However, I expected the second one would be accepted for oral presentation, as I believe it is more important and relevant to the area and probably to the track and the conference in general. It is also about my primary work, which is more sophisticated and robust than the first one, and I think it would be better for me to present it orally.
But I understand the conference committee have their evaluation and criteria for deciding the way of presentation for each abstract.
Shall I just accept this allocation, which is good anyway? Or is it common and accepted to request, with justification, that they swap the two abstracts - provided they didn't print and disseminate the program yet?
