I'd bump this again
.
Today I got my Redback Paradox LE
(and long awaited mallet ;-) ) and as soon I got it I took out Dukes ball I have and checked its ping so after that I started knocking and knocked the bat whenever I was able to throughout the day
(still not fully knocked) so at the end of the day I again bounced the ball and saw clear difference between before knocking and after, again as I said its not fully knocked but there is big difference in ping.
It is quite amazing to see how big of a difference knocking makes.
