I’ve been going through secondary rollers like crazy. The surface the rollers roll on is worn bad. So I’m looking at buying a new secondary from Polaris. But I’m also tossing around the idea of throwing a stm secondary on. The only reason I would want it is if it would eliminate any future roller issues. Seems like the two roller setup is less than ideal. So from people that have experience with this secondary what are your thoughts?i plan on running it with the stock primary. Thanks for your input.
