I always get a kick from the bearing hype. First of all, if a bearing isn't made in the USA, then it isn't an ABEC anything. ABEC is an American industrial engineering group, yet the internet and catalogues are full of "ABEC 7" bearings from China....
Secondly, you certainly don't need and ABEC 7 bearing for a fishing reel unless you are going to be running it at like 15,000 RPM for hours at a time. The only 2 bearings in a reel that might benefit from a bearing that highly rated would be the spool bearings.
If you notice, the excellent bearings sold by ZPI, Hedgehog and (and others) have no such bogus ABEC rating, They are top drawer bearings, but being made in Japan, they have no need to pretend to be ABEC rated.
In my opinion the Boca bearings are somewhat of a racket. They charge as much for them as Hedgehog and they deliver mostly Chinese "Orange seal" bearings with an ABEC rating that they could never have. Save your money and just go to E-bay, Allie Xpress, or Amazon and buy the Chinese "Orange seals" from the source in bulk for less than a buck apiece. Sort the junk bearings out and you end up with the same thing. I'm just not paying those guys 10 bucks a piece to sort Chinese bearings for me.
Most of my reels (40+) have either Hedgehog or ZPI Ceramic hybrids and I think that it usually does make a noticeable difference. Boca? Not so much.
