Clat trac vs. SS springs vs 4 link

Ok I'm going to be setting up the suspension on my 73 Duster. I'm definatltly moving the springs in for bigger tires and throwing my set of slapper bars in the trash can. The question is what is the best way to get the car to hook hard. It's going to be street driven with some track time. I'm willing to give up ride quality for a harder launching car. I see alot of people talking about the Cal tracs and they seem like they'd work good. Would they be better then a four link? How good would just running mopars super stock springs be? Which way would you go?
