So is she good, should I get excited about her?
Haha, in my humble opinion, yes she is, and yes you should. @Snowman can give you his thoughts on her, too. But honestly, with Shine being "real" women's wrestling, I'd welcome practically any of their wrestlers to TNA gladly. They aren't just eye candy there. If you think you'd care to see one of their shows, I can try to hook you up. If not, just get pumped and look forward to seeing her in TNA.
For now, here's the Wiki page on Jessicka Havok.
