From the very first day that I received my Absolute, got it drilled and began throwing it, I have not once picked up my Ultimate.  The AI covers absolutely (no pun intended) everything that I have encounted so far.  You can stay outside and still clear the heads with not problem or you can chase the oil line moving deeper and deeper as necessary.  Ruff Buff is absolutely incredible.
Anyone in the nation know how many games, give or take, before you have to get ruff buff applied again?   This one is hands down, Ball of the year, and probably for some to come.
