BEST CYLINDER - MHR rep / POLINI corsa / ITALKIT aliminium

[zip70]

Hello all i want to upgrade from polini sport 70 cylinder, what do you think is best and why out of MHR replica, Polini Corsa or Italkit Aliminium ?? And why? I thought corsa might b good cos it is cast iron = last longer??

also how long until u need to change piston rings on the cylinders?

cheers

Tom
