True. If you read my stator log I did buy a new Wassell so I could compare it against my collection of Lucas rotors to see how they stood-up. One rotor wants chucking in the bin but generally the rest compare quite well despite being 40-50 years older than the Wassell.
Another way of looking at this then is that compared to a new Wassell rotor a new Sparx rotor is more powerful.
