Poston U/D or RJC Billet pullies

[FastRegalWE2]

Was wondering how many guys run underdrive pullies on the street with no probs and which would be "better" for the street, RJC pullies which I know are not UD or the UD pullies. I got to see Jasons pullies when I met him at his home and they are just outstanding pullies. Both styles were great. Just dont know which I should go with on my street car.
TIA

IMO there is no need for underdrive pulleys. Jason's pulleys as you know are top notch. They weigh next to nothing also. I'd go with Jason's.
