I personally like my Exalt tank cover over the BlackStar because it does cover up the tank a little further.
Both are a PITA to get on and once you are used to them they are easy to do. You actually use the same technique to get them on. Flip the tank cover inside out and roll it onto the tank. The Exalt is thinner then the Blackstar but is longer and covers more of the tank.
Again like Blackrain said, I would rather cover my tank up a bit more then have a hole drilled into it when I go to hydro-test it.
PS... I already have marks in my tank cover from diving into bunkers. Better marks in the cover then marks in the tank right?
