I would suggest that dude ride whatever frames fits him.

Now back to the general comment of "bikes are made for riding, not aesthetic value."

What's wrong with having both?

The particular bike in question looks awkward to me because it's so large. Obviously nothing can be done about that. But in general, a lot of people **** on people who care about how their bike looks. As if people who put thought into the look of their bike aren't serious riders. That's crap.
