DSE or HEIDTS Rear Suspension

[RPryor69]

I am looking to install a new coil over rear supsension in my 69 Camaro and I was wondering which one I should install since I have installed the DSE deep tubs already. I am looking for good handling and the best ability to plant some sticky tires to the ground. The difficulty of installation is not a problem for me. They both look very easy to install. Please some feedback on the pros and cons of these two systems. Or do you have a better idea.
