Hi mul211
This is general rule,
1)avoid any spring if possible,
2)use variable spring than constant spring

When variable spring is really required, it has to be, project specification can not dictate not to use variable spring.

However some trick can be use to avoid costly constant spring
1)Relocate spring support location (point where vertical movement little less)
2)Select spring manually by installed load & stiffness.
3)check vendor catalogue & try selecting less stiffness spring ( than Caesar selected) for same load.

If you wish for manual selection spring, Caesar will not cross check that, ensure load range, stiffness, load variation are within acceptable limit.
