To be honest i dont notice much difference between the 2 systems both are very good, but im not a top racer.

What turn vortex motor was this?i just bought a 6.5 to run on my mamba yet it wont set off, it needs a nudge or it jsut sits there juddering. Is this the motor or could it be settings on the speedo?

Back on topic. From the side lines iv seen that the novak systems are very quick, the motors are very reliable and the speedos seem to work very well, it appears the LRP/Nosram motors are slightly quicker than novaks but seem to suffer with reliability, as do the LRP/Nosram speedo's even if they are more advanced.

My biased opinion is the mamba speedo (extremely flexible and has a huge array of settings) with an orion vortex motor that works but thats just me, when my motor ran tonight i was seriouly impressed.
