I'm part of the Shimano posse and use only their reels. My bait casters are Curados of various speeds. I had a couple that weren't casting as good as I wanted so I took out the spool bearings soaked, cleaned and relubed them. They cast better but were still making a bit of noise.
So I thought that I would clean the brake drum. I test cast them in the yard a few times and got the average cast length. Then I sprayed some NAPA silicone on a Q Tip and ran it around the drum a few times. When I test cast them again both of them would cast about 15 reel handle revolutions farther and they were more quiet than before. I think that must relate to about 25-30 more distance which should help me in open clear water.
Whoda thunk it.
