SRD Assassin's vs Cal-Trac`s?

Anyone here running SRD Assassin bars on their A Body? If so any feedback on quality, Fit, clearance and so forth??

Trying to decide between these and Caltracs. The cost is basically the same but it appears that SRD has more adjustment and the big thing is they supposedly work with my existing Leaf springs where as I would need to also buy Mono Leafs if I went with Cal-tracs more than doubling the total cost.

Opinions?? Anyone have experience with both?
