Response to Well, to restate the basics. 1. A lighter striker will need a heavier...

..getting enough spring to speed a lite striker up to the point where is get back to the same energy as a heavy striker. Even taking some weight from the front end of the striker in order to lengthen stroke a bit hasn't fully made up the energy. Many just have a small area for a striker spring to operate, so when increasing striker tension, end up with a very stiff spring.
