ISKA's website is not very good... strikeforce is the name of a series of fights. alot of the espn stuff in 1-4 years old, another reason why you may not see guys on their website. k-1 and iska are to seperate companies. but when k-1 holds events in the US. they actually have a contact to have iska run the show for them under the k-1 name. using k-1 usa fighters.
