Bump.
This really is a serious question.
Reasons:
1) Women almost always say a bald head is way hotter than a combover.
2) All these guys are "balding". Except PSH has been like that for 10+ years, Thom Yorke has had that fucked up combover for the last 10 years at least, and Andrew Bird had a much lower hair line 10 years ago. But, if their hair is styled correctly, I think they all look fine. Wondering if these guys have obvious combovers or not.
Secondly, I think the decision to shave is sort of a cost/benefit analysis. Or, a lesser of two evils. Now, some guys look better shaved (Michael Stipe, Billy Corgan), but most guys would prefer hair. I think that the decision to shave should be made when you can honestly say that a shaved head looks better than your thinning hair. I'm just not sure those guys are there yet. Flea is another one I would add to that list.
