I lubed and filmed them. Tried them stock, lubed, and lubed and filmed. I would say that that light lubing (especially on the spring and the stem and rails) is a good idea. The springs ping quite a bit without lube and there is scratchiness on the stem that will improve with lube. Just be careful to not lube the leaf and legs or you will lose some of the tactility. I would say filming is not needed with these switched but adding a 0.15mm or 0.3mm film while you have the switch open can't hurt.
