Torsion bars the bigger the better???

I live in Michigan where the roads really suck, have 18's and the 1.06 Firm Feel Torsion bars and the Fox/Hotchkis Shocks. I doubt anyone would think it rides too stiff. I have RMS strut rods and Hotchkis control arms where there is NO bushing at all (spherical rod end), and poly lower bushings as well as rear spring bushings.
