Step back in what regard? Power potential, yes. Reliability, could be argued either way. If you had a SFT, you wouldn't have shredded a bronze gear because there wouldn't be one. SFT may have issues on break-in with current lifters if they aren't made right, but a roller is a more complex system and has more failure opportunities. Everyone has different opinions and experiences on the topic. Both systems can work great, or be a nightmare if something breaks.
