I just received my Proform 1.6 roller rockers. I’m sending them back and here is why. 1st, they are not marked anywhere that they are 1.6, not even on the package....so are they? 2nd, when I grab the big roller I can rock the body quite a bit around the bearing.....that can’t be good. So, do I have to go with narrow body or will standard body work too? I’m thinking of going with Scorpions full roller, narrow body, self aligning 1.6. Any comments? Thanks

Narrow body, and self-aligning are the only ones that waill work. The best roller rockers are Crane Gold Race. Remember, rocker arm weight is crucial, the lighter the better and don't believe those advertisements for the so-called steel roller rockers.
