VR with Mamiya ZD

A while ago I evaluated the user of the Mamiya ZD wich the 24mm lens (link) over the Canon 1Ds Sigma 8mm combo.

Facts 1Ds with Sigma 8mm:
3 or 4 images (4.062 x 2.704 pixel), fisheye
Resulting in a 5.000 x 2.500 equirectangular image.
Pro:
Full 360x180 degree coverage with 3 images.
Can be shot using monopod.
Con:
Lower resolution and image quality due to fisheye

Facts Mamiya ZD with ULD Sekor 24mm:
6 fullframe fishey images with 4.008 x 5.336 pixel each results

Resulting in a 16.500 x 5.200 equirectangular image.
Pro:
Crisp result, high resolution and quality image.
Con:
Requires shooting using tripod.
Does not cover zenith and nadir. Requires a sturdy panorama head with this gear, maybe Nodalninja 5, to shot up and down.

Sample: Stitched with PTGui 8.0.2 and converted to Flash with Pano2VR 2.2 beta4. Crop and Touchup Photoshop CS3.
