I can t stand it. Abec7 bearings even abec5 increase casting distance, spool smoothness, and overall put a supercharger on your reel. This upgrade is a big jump in performance. If you are not good at casting you will never see any difference. It's not for everyone. I have seen first hand the difference and can say its big. For the most noticeable gains a supertune is a great help. All my reels have abec7 or 5 depending on what it's for. Drag set is a no brainier if you are already in there. There are many ways to get bearings, Boca, Hawgtech,Dads ol Tackle, smooth drag, HP bearings even sells kits. If you are happy w your reel the way it was when you got it,then clean and replace. Remember quality does not cost it pays. But it's not for everyone
