Howe dual piston calipers?

[Ackattack]

I originally was going to use a big brake kit on my project truck, but now I'm thinking of using a stock style disc brake setup so that I can still run a 15" drag tire/wheel combo on the front.

I remember reading about the Howe dual piston caliper that is supposed to be a replacement type part for our stock calipers, seen here:

Is any one running these, and what is their opinion of them.

I'm going to be running drilled/slotted rotors (to match the back ones) along with Hawk HPS pads, so I'm thinking I really won't need a big brake kit with the upgraded calipers and pads.
