Personally i used to think that 7 strings were the "devil" but after seeing Vai and Petrucci make some absolutly amazing music on them i really started to think "hey maybe these aren't so bad". Basically i think the bands that do abuse the 7 banger should go back to the 6 style, and people like vai need to keep innovating on them. But that's just my stupid opinion so who cares anyways right ? =Þ
