but there is a reason that track racers don't use Omniums: they 'give' more due to the spindle length (I know, there is no bottom bracket spindle here, just the bar connecting the two crank arms like on a road bike). The Sugino cranks are built to use a shorter spindle to reduce bending and the potential for breaking. The Omnium cranks are more likely to break due to the lenght of the spindle. And, they are going to give a softer pedal stroke due to the fact that the bearings are on the outside of the bracket casing. This is also why Suginos are NJS certified and Omniums are not. Therefore, Sugino's are a higher quality crank.
