Anyone heard of TG's Yellow Rocket Fuel or TG's Ceramic Rocket Bearings?

Yep.

and??? good? bad?

LOL, very good.  Watch out, read the product descriptions, and use the "high speed" stuff with caution.  Tournament Grade needs to be replenished after every use.  Keep in mind, they in Europe as well.

Right now, Boca is running promotions that pretty much make going elsewhere pointless.

ok, good. I'm thinking about having my reels serviced by a guy who uses TG's Yellow Rocket Fuel and he has TG's Ceramic Rocket Bearings available. I think I'll ask if he will install Boca bearings if I send them along. Just to be clear, the Yellow Label stuff will last until my next maintenance or will I need to add some in between?

Any recommendations on which Boca's I should be looking at? FWIW, it would be for a Revo STX, Revo Premier, Citica E, and Daiwa Fuego.

Boca Orange Seal.  Hope your guy knows how to set them up.

oh, are they different than other bearings?

They are sealed, not shielded.  Boca Lightning are closer to what TG Rockets.

The Lightnings are ABEC-5, correct? That would be a decent upgrade from the stock bearings in my reels, correct?

oh, and thanks for putting up with my ignorance, John. I truly do appreciate the expertise.

Yes, but they are ceramic as well. Ceramic balls, steel cages and races.
