Thank you. Not intending to be dense: this sounds like a weaker version of what I already have, and what I already have should not be shot because of risk to the ejectors. What's unclear to me is where the tipping point is for risk vs. no risk. Is it the force of the process of ejection? By using weaker springs the reduction in force eliminates the risk of damage?
