This is a Panoweaver forum. Panoweaver stitches Fisheye images only. This might account for the no reply. Also I had to read your post/questions many times before I could make sense of them as I did not find them very clear. You can of course crop the top and bottom off to create a cylindrical panorama. Any panohead capable of  taking the pictures for a spherical panorama can be used for a cylindrical panorama. So long as you can position the camera for the correct entrance pupil (nodal point) of that particular lens being used. If you are planning to use a longer styled lens I would suggest you go with the www.agnos.com MrotatorTCPLong.

Hopefully this is of some help to you.
