I think I will look at it like this...we used to run a less expensive brake pad that had incredible bit put if you used more than 2 toes the flat spotted tires added up! We went to pads that cost 30% more but saved us at least one set of ruined tires per year...you do the math!
I too like Jim have had good luck with repacked OEM hubs,,,without even changing the ball bearings. But give me something that may be able to repack in 10 minutes, more metal than OEM(flange breaking)and pretty bullet proof...I will spend the money! And if they last twice as long as the other option at least you're even!
