Little too much information to pass on. A Brutal Nightmare has great backend, but it doesn't have length, it hooks a ton. Lanes aren't oiled by hand, it's done by a machine, but they may seem different at times depending on if they've been bowled on or not. Bowling balls pick oil up off the lanes and/or move it around. If you want the ball to go long and be strong on the backend, tell your driller that. He will take care of it from there.
