Anybody try ceramic bearings in baitcaster reels?

Yes. Get the Boca and be done with it.

Got them put in my E series Curado and its smoothern shite, chunk a frog a mile.

They're worth it imo, I have them in all of the reels we use regularly. They hold up longer and cast further, they are louder especially if you get the unshielded version, be sure to plan on adjusting the spool breaks or you'll have the backlashes issues mentioned above.

Have any of you tried the cheap ones from ebay ? I am probably gonna supertune and change bearings in my reels, but no way I'm spending 500.00 for bearings (I have 20 reels now).

I did a supertune and used the eBay bearings in a Curado 201E7 I have. The supertune made a noticeable difference but I wish I'd have just spend the extra money on a quality set of bearings. Those cheaper bearings didn't seem to perform much better than the factory installed bearings.

Wish I had known. I took apart a Pro Qualifier I bought back in April 2 nights ago and the factory bearings barely spin. I assume they are full of grease. Whatever I buy I want the removable shields so I can clean and lube them easily. I don't tournament fish anymore and have lots of time to tinker with them. This is all new to me but I figure it's another skill to have even if I can't work anymore.

I might take that offer and supertune my 201E7 and 51MG. I have eBay bearing sitting aside for both but haven't installed them because I wasn't completely happy with the eBay bearings on a 200E7 that I installed and eBayed.
