I felt like I was drunk as I panned around that last one!

Setting vert points would level it out unless you wanted it wavy.
When I saw It's all wavy and crappy I thougt it would be nice to leave it that way, as it would reflect my druggy mug. :P
I am trying to see the seams and look all connected perfectly.
They didn't match perfectly, I had to do some photoshop work. I think I didn't adjust my panohead properly, I will have to do that if I want to save that extra work.
Will you kindly share what kind of camera and lens you used and the panohead if it is motorized. I am just using dlsr and 12-24 lens at 12mm, a panusaurus manual panohead, so I take 20 images in a panorama, seams are many so I have a hard time joining them perfectly specially interior of a house. Thank you very much and best regards.
I am using a Peleng 8mm Fisheye on an Olympus E-510 with the Panosauras as well. For each panorama I shoot 18 images. I actually had to take less, but I like working with more substance for stitching and retouching.
