It does not lower it or raise it, if that's what you're asking? It does make the entire racquet more solid feeling and softer. So I guess the sweetspot feels more soft and solid.
The stock blade seems to have quite a bit of weight at 10&2 (from my estimation) and considering this one was even balanced, I added enough to bring it to 8pts. HL. I, personally, would not add this much weight to the handle of a more HL racquet.
EDIT: Now that I think about it, and recollect, on how the racquet played before the mods, the sweet spot seems/feels bigger. It was pretty high, on the string-bed, stock and now it seems to have moved ever so slightly south, in essence enlarging the center.
