Has anyone used steel rods running 20-28# boost? Putting my stuff back together soon, and have the option of going either way-Oliver Max or GRP pro material. BBC Big M billet caps, Callies Magnum crank. I ran 15-19# with the Olivers last year and the bearings look great. I know aluminum rods are easier on the bearings and crank. Just wondering if anyone has experience of using steel rods with this kind of boost.
