I am not familiar with many of the urethanes, although I currently use a Blue Hammer, and have had the Natural prior to that. The thing to be careful of on short sport patterns is the amount of head oil. No matter what you do with the surface on a urethane, carrydown can become a big issue. I would go with any urethane that has a core you like, and not try to get too aggressive with the surface. Also depending on the length of the pattern, you may find a low flare solid reactive such as the IQ tour or Arson Low flare as effective as a urethane.
