Shout,
I agree with Dusty. The Blazing is no more; it was irregular in any case.
From my point of view, with the proper surface and drilling, the Intense can replace the Original for mediums. The original also needs the proper surface and drilling to cover mediums for anyone's particular release + ball speed. Both are VERY adaptable, as far as I have seen.
SLay/R is good for lights to medium-lights.
