Shock selection help

OK I was wondering for better handling, not track or drag racing what is a good shock to use on an A body and a 70 cuda E body?

I need better handling and still want decent ride, but firm is OK.

Was looking at these...http://www.summitracing.com/parts/EDL-33840/

Edelbrock Performer IAS Monotube Shocks (seems these are stiffer)
and
Edelbrock Classic IAS Shocks

anyone use these and can detail the diff in the 2 lines for me?

thanks!
