I first preferred ball lock biners, until I started having problems with sticking and delayed locking. So I switched to the William TriAct M23. But I noticed on one that the spring on the twisting orange sleeve is releasing before the gate returns all the way, preventing the gate from closing automatically. I keep my biners clean and dry. So my questions:

What are peoples' preferences for locking biners, what are people using to clean them, and where are they buying them?
