The UR pulley being the lighter of the 2. I use UR pulleys because they are made in the USA, using quality materials and known quality manufacturing controls. I have NEVER had one have a missing timing mark or be marked in the wrong spot - both of which could cost you a motor. Take a look in classifieds - used UR pulleys turn up @ fair prices pretty regularly. I also recommend using HI water pump pulley if you opt to use a under drive crank pulley of any brand.
