Most Helpful Guy
I find the rocker type generally betrays effort in coolness if you know how to look at it right ;)
You shouldn't pick who to be based on what guys might find attractive.
It's true that at your age people will tend to approach those who match their own music/fashion style the most. They may find others attractive, but assume they wouldn't want to date.
Be yourself, it's possible to look attractive with any style.
