i'm using link bar solid rollers in a non roller block now, no issues, checked the
oil band before use to make sure everything was good on the base and at lift using a roller cam. i have heard and will perpetrate the fact or myth that some don't like the small base retro cams as they flex with the rumor of breaking. unless i already had and was set up for the spider/dog bone stuff i would probably use link bar, just looks better to me. bob has some good info above.
