shaft comparisons Matrix ozik White tie 5x3

I currently have a Matrix Ozik white tie 5x3 S flex shaft in my driver, it goes like a rocket with the M2 /1 head, but due to the stupid head cover the shaft has worn extensively though the white cover down to the black underneath and is quite pitted.

Maxrix went bust I think and taken over, but new company don't do that version anymore.

anyone know of a similar shaft to this one or of a way of finding out a shaft of similar profile?
