Well, after working with the HP-C+ and Sotar, I still prefer the spring tension for the valve on the Sotar. Debating on what to do, I looked up the price for the spring ($20.00 U.S.) and decided to go a different route.
Not sure where you are based but @Lion-Art sells these from his shop in The Netherlands for 5 euros each. I just ordered a couple for my HP C+. And shipping cost to UK is very good too.
I've heard that some people have replaced springs using ones out of retractable pens but I don't think I would want to try that.
Out of curiosity what is the diameter of the spring.
Thanks for sharing your experience.
