Unorthodox Pulleys - Ultra S vs. Ultra SC

Ok guys, I have been browsing the 1/4-1/8 mile forums and most of the guys breaching the low 14s/high 13s are all using pulleys with other bolt-ons. I just went to unorthodox racing website and I noticed they have two sets for the I35. I want to buy the pulleys ASAP, but the Ultra S cost 233.00 and weighs 2lbs and the Ultra SC cost 250.00 and weighs 3lbs. Is there a big difference in the pulleys? How much power gain are we talking here for either one? Are any of you guys using the pulley?

Thanks
