Penn 650SS Line Roller retrofit?

In a long run you'll be better off. If you do a lot of fishing, just clean it often and it will always perform as it should.

I'm giving up on a ball bearing roller retrofit.  Just sticking with the original roller and I'll work on improving its rotational qualities in my spare time.

Have to agree with Sal here.
Wise decision. 
These line rollers work great as they are,it's only when ball bearings are introduced that they have issues.
An annual service on my 650SS is all it ever needs and without having to replace bb's every year.
