Well SSDiv6, you may have access to scientific instruments and labs, but I knew from the get-go when I took a Speed-Pro/TRW AMC rocker and "thunked" it with my fingernail and it went "dunk" and the OEM rocker went "diiiinggg" , then surely the factory offering was better . Although that did lead to a rockwell hardness test which confirmed a huge difference as I suspected...
