I get the gist of your quest.
But i guess, the most important thing is that whoever`s the leader, in the technicalibility aspect, he/she should be able to have a gd listening ear, meaning to say that he/she will be able to advise the band in terms of their overall sound balancing,tone,tempo etc as a whole. Sound balance is very impt in a band...this one iam sure vio agree with me :wink:
