Any more details on the other team that might be relevant, e.g., what size tires and PSI were they using, how many miles on the wheels, are they a lightweight team, heavy-weight, USCF Cat 1 & 2 hammerheads.... ???

As for the '08 updates to the Rolf Prima Vigor rims, they reduced the rim height from 34mm to 30mm (which is the standard height of the Velocity Deep-V and Topolino rims), increased the height of the brake track to match the width of most brake blocks as the pre-08 models had a very, very narrow track, and they added material to the spoke bed to mitigate problems with spoke pull-through. In other words they reduced the weight and (at least in theory) made the spoke bed stronger. Oh yeah, and they changed the very nice and tastefully understated decals to some really blinged-out, psuedo-chrome looking lettering.
