A devilock with sideburns was fun. Mine never got much longer than my nose. I dunno, everyone loved it, but I kept cutting it from the back until it was almost like bangs. Not sure how fun a long ass one would be. Probably really
I had one before I had a mohawk. I left the rest of my hair a few inches long, so it looked a bit weird. It was long enough to go past my chin though. I would gel it down, but it really got in the way. So after awhile I tucked it behind my ear, but that made me look like a pretty boy, so I cut it off.
It can be split+double hawks. Thats a cool way. Personally, they're a lot of fun. Shaving the back of my hawk would feel like suicide if I totally went for it again. A couple months ago I had one and two fins on one side.
