Buzz, the Cobra Classic seat with removable headrest looks like a very good option.
I do agree that padded roll bars are not as clean looking as bare tubing.
However, to my eyes, the only thing uglier than a padded rollbar (or two) is the caved in skull of your wife/girlfriend/child/relative/neighbor/friend, or yourself. Brain damage is UGLY.
Some things are worse than death for the injured person and the family.
I think a removable padded headrest/rollbar cover would be an ideal solution if someone could make one that looks good and can be mounted and removed easily and quickly. Perhaps something that slips down over the roll bar and fastened with quick pins? Make it look like the modern race seats with side impact wings even.
I am sure the Kirkham's could design something that looks excellent, works as intended, and would be wanted by many.
