Mono Leaf V.S. Coil Over ????

[Dirt Knife]

What would the effect be running Fast Boys Leaf with RR coil over behind locked to axel tube.
The Mono leaf is floated.

A lighter mono leaf say a 37# with a stiffer say 175-200# coil
Or a 68# mono leaf with say a 100-125# coil

the percentages stay the same Chrysler leafs with Afco pivot in front slider box on back.

Thanks
