Do you need a roller block with solid rollers. I have not seen solid rollers that use the factory roller alignment system. They generally use link bar rollers. The other issue is running 11:1 these days as the push to go electrons is only going to get worse. Personnally I think the woke numbnutz that are working the carbon climate strategy are pissing on an electric fence. We have had global warming for something like 12,000 years, since the end of the last iceage. Enough on that rant.
