I started off using his version 1 then switched to version 2, but honestly there is so little difference...
I do not have a difficult time with pitch speed at 20 cos i play with the camera behind the pitcher so you hardly notice the difference between 10 and 20... it is even more realistic to see a faster pitch...
What i really like from carew's sliders is variety... you can really see every kind of hit (center field, opposite field..) and there are a lot of extra base hits (3 days ago i played with the marlins vs the mets and i finished the game with 5 hits, none of them a single... 1 HR, 1 3b and 3 2b...)...
