Underdriving the OEM pump is fine, but if you upgrade the pump and then underdrive it... you're back to OEM flow, but you gained from removing the parasitic drag.
I just did this mod myself. I purchased the set from Turner Motor Sports and it came with 4 pulleys. The extra one they sent was to properly match up the alternator pulley and they sent a box to mail the one I didn't use back for a refund. I also installed the Stewart water pump. Really, I don't notice anything different but I will say that I'm extremely confident I won't be sitting on the side of the road somewhere do to a cooling system issue. I couldn't believe how cheap the OEM pulleys and water pump were once I pulled them off and compared them to the new products. I would say that any of the sets listed will do the job just fine.
