Digital BW, The Print

I'm planning an exhibition next year and, as part of it, I'd like to
print some large Hasselblad Xpan (panoramic) images.

I'm thinking maybe 1.5m high.  The prints need to have impact,
dramatic effect.

It makes sense to print it digitally - probably in a professional lab
(my R2400 won't quite be able to print big enough - although, with a
roll of paper, it would go close).

I'm struggling with how to do it and how to present it.  One
possibility is to print on canvas then stretch over a frame.  Another
possibility is just to print on paper and use glassine pins to nail
the image to the wall

BTW, the images are largely of Vietnam and Cambodia - but it would
seem a little cliched to use a scroll arrangement (e.g round wood at
top and bottom).

Does anyone have any thoughts?
