I have noticed the twisted effect where the fronds join the midrib,leaving gaps.
'Verona'--dense, 3- or 4-pinnate fronds very hanging (pendent) .. sounds possible? Photos are in short supply!

I found one on a French site called Nephrolepis exaltata 'Burkwoodii' but I can't find it anywhere else. The desctiption translated doesn't quite come out right, but some of it sounds OK! "Fronds erect to the side segments very branched, overlapping form. Houseplant. Port compact, excellent plant for suspension." There is a photo.
