What are you going to do with your truck? Highly mod? DS slightly mod and better gas milage BD.
It all depends on what you plan on doing.

That's where I started. The Bully worked great for me. The DS with Hemifever just tightened every thing up.
It is a pain in the ass to get loaded up. But once it is, it's a different truck.
If your really just doing those mods the BD will work well for you. And you can get them on sale here all the time for a couple hundo.
