who cares where they are made as long as they perform well for you. Both make some good strings, you just need to find out which is best for you, which it seems you already have.
Personally, I prefer the black magic over any other poly. Great string.
On another note, at several futures I string at this year there were quite a bit of players using the Genesis (Black Magic/Typhoon). Also, not sure if Karlovic is using it (Genesis),,,,, I think you meant Gabashavilli,,,,,,,,,,,, and also, Wayne Odesnik uses it.
