leafsprings - what would you recommend

So are you all saying to NOT go with the Mopar XHD spring set (for general driver/occasional track)? Or you just haven't used them? That's what I was about to order, but now maybe I will go with ones from this springsnthings.com place...?

The xhd are just fine for a street/strip car thats what i use on my '70 duster problem is nothing is made like they use to be,mine are the older version(not made in Mexico):-D:-D
