Super Stocks Springs have i reached the limit?

FWIW-I weighed my old leafs at 72 lbs (XHD setup of some kind) and the Calvert monos at 48 lbs (they’re pretty thick steel). Pinion snubber was 5 lbs and the caltracs were 15 lbs. So savings was only 16 lbs for the setup change. Can’t speak for the SS, they may be a little heavier with more length to get the arch they have. I got way better hook and consistency (but compare the two systems and it’s pretty obvious why). Was only mid 11s with it, so power is waaayyyy less than OP.
Curious...were these split mono's or straight single mono's?
