Pitch and Rocker Advice

OLD SKATE: BAUER VAPOR XXXX / SIZE 8D / TWO HEEL LIFT PLATES / 13+1 ROCKER

NEW SKATE: BAUER VAPOR X:60 / SIZE 7.5D

I was told that Bauer went with a higher (steeper) pitch on the X:60 as compared to the XXXX. I am wondering (due to the steeper pitch and shorter steel length on the 7.5 size) how many heel lift plates I should put in and what I should get them rockered at to make them feel the same as my pitch and steel length on the XXXX's?

Thanks in advance...
