I was talking to a guy the other day that says he always upgrades his reel bearings so his reels cast a mile. Me on the other hand I take the reel out of the box and spool line on it and use it. Is there any real benefits to upgrading bearings and where do you get them. Most of my reels are ABU Revo Rockets (Gen3 and Gen4) or Revo STX SHS reels.
