Big-T-

Personally I do both wide grip and narrow grip(palms facing) more so narrow to hit my bi's too...But another one I like to do is kneeling lat pull downs,where one knee is on the ground and the other is pressed against the seat also use a V shaped pull bar for this.Absolutely great but you really need to glue yourself down as when going heavy the weight can pull you back up but a great exercise for me...
