Larry,
I weighed the aircraft with the cable system installed using a bathroom scale.
After the remove and replace for the pushrod system, weighed again with the
same bathroom scale. Granted that may have some errors due to internal
repeatability and accuracy, plus my ability to block up the wheels properly,
etc. I also weighed all the stuff removed and all the stuff installed
including mounting brackets, bolts, pulleys, cable shackles, cables,
turnbuckles, pushrods, rod ends, etc. The difference was still just about 6
pounds less. I had expected some weight gain. My object was not for weight
reduction. I am looking for long-term reliability and functionality. I had
installed a flaperon system also, but took that out. That got to complicated.
I am staying with the pushrods for elevator and ailerons. I have since added
another 4.5 pounds for elevator balancing, which includes 2.6 pounds of lead.

Sid,
How did you measure the 6 pounds saved? Several components
stay in the system , pushrods or cable.
It seems to me that if you removed all the cable in the system and
replaced it with nothing you'd have trouble dropping 6 pounds.
I'm not questioning your honesty here, just your scales. :-)
