I didn't try cleaning them, there was a brownish colored ring along the seam on the side of the bearings.
Read up on the difference between the ABEC values.....I was just curious how much a difference I would notice between the two. I can get a pair of ABEC 7 for $30 or 5 pair of the ABEC 5 for $50. It's a difference of about $20 a pair and would I notice, one way or the other, in reel performance? Thanks for the help.
