You could try the bearing upgrade. Not a bad idea at all.
I would at least try loosening the tension knob first though. Also, if you don't fit the pieces back just so after cleaning, that may cause some of this. Also, sand and grit find their way inside- some how.
I see no advantage to using ceramics without oil. The hybrids are ceramic balls within a stainless steel chase. Yes it works, but what are you accomplishing ?
You end up trying to achieve a balance by adjusting something else- elsewhere. The idea with these reels is to find the best overall setup possible.
There are several ways to tune these reels. Line diameter, spool fill, oil, and magnets. Change any one, and the others may need changing to meet the new setup.
Control is needed during the early stages of flight. Here things are eratic and chaotic and you may not get off a good swing. The line is flipping around, flapping and even pulling at differing speeds. This causes the spool to spin fast, then slower, then fast again really quickly. These changes in rotational speeds cause birdsnests. So the best control, will be the one that changes to meet the needs of the spool during all phases of the cast.
Oil is that excellent control. It is thick and heavy and slows the spool early on, then it thins out and releases the spool to spin faster later into the cast. Hard to beat that. Red Rocket does this very well. Yellow Rocket not bad either. There are also many other oils that will give the same performance, maybe even better. But heavy at first, thin later is an excellent way to control varying spool rpms.
Line diameter and spool fill can be used to tame or loosen a spools speed. Overfill the spool it spins faster, thin down the line diameter it spins faster. Thicken the line diameter or underfill the spool, you will slow the rpms- naturally. Of course, line balance when filling the spool and your ability to wind the line back on evenly also enter into this because they too can cause the spool to spin at differing speeds = birdsnesting.
If you go with the hybrids, keep the oil, and look to gain speed elsewhere. The oil will act like a stabilizer and you may be able to simply slide the magnets off a bit to get the extra speed you need. Skip the oil and this basic control is also gone, and you may start putting on more magnets to avoid mishaps. The oil will not impede your ability to gain distance- trust me. Only you can do that. LOL
Tournament casters get advantages from no oil, but then again, they don't mind birdsnesting. They do it all the time. They are looking to ride the raged edge. You on the other hand have just spent an hour getting into your spot, and maybe the fish are biting fast and furious- can you afford to foul the reel ?
BTW- have you cleaned and lubed the other bearings ? There are actually four inside there. Try that also.
