For a pano shot a wide angle is a bad idea as it distorts more towards the edges. Also, when making a pano, take all your shots in portrait orientation as there is less distortion on the longer sides because they are further from the edges of the image circle, this way when you stitch your images together you get more height, giving a much more pleasing aspect ratio, and you get much better stitches with less distortion.
As this one goes, it's quite nice, the stitching is good (if there is stitchiong and it is not a crop), but I don't like the aspect ratio. It either needs to be either bigger vertically, or narrower horizontally. It's really bugging me.
Hope that helps.
