From what I can tell from all of the years of seeing these overseas releases is that ball companies use the overseas market as a testing ground for different core/cover/finish combinations. Then use real life feedback to use on the US market balls. Now, I could be wrong if the overseas market brings in more cash for them than the US market, then if thats the case then I have no idea why they give the overseas peeps such cool toys lol.
I wonder how this ball would work on your THS here in the states compared to the original Invasion? I'm guessing like guff said, would probably roll out on anything except heavy oil, which most of us don't see on regular occasions.
