There comes a point where you just get too old to have long hair. I hate to say it, but I think a lot of the guys in the band are past that point. Mangini and Petrucci, at least. It looks a little ratty, TBH. I wish JP would go back to the shorter look of the early 2000s.
LaBrie can still sort of rock it, and Myung's hair is so straight, he can probably get away with it forever.
I think it's funny and ironic that you said that some guys are too old to have long hair, but that James, who is 52, still looks good that way, but Petrucci, who is still in his 40's, should cut it.
My two cents:
-I think James looks okay, but maybe he should try the shorter hairstyle like he had during the FII tour, just to see how it goes.
-I agree that Mangini's hair is awfully "ratty," and he should maybe go back to the shorter style that I've seen in some of those older pictures of him.
-It would be interesting to see Myung try a really short hairstyle. He looks too much like a girl.
-Petrucci looks okay, as long as he keeps his BEARD trimmed. The "crew-cut" look he had back around '04 made him look like a little boy, but a shorter haircut might look good, as long as it isn't THAT short.
-I wish Jordan would at least let a little "fuzz" grow on top of his head. I've never really liked or gotten used to the skin job.
