Found an interesting fight between Kharitonov and Finland's highly rated giant Robert Helenius at the Geebee tournament last year. http://www.dailymotion.com/video/x2efw8_sergei-kharitonov-vs-robert-heleniu_sport
Thanks for sharing. Indeed Helenius is gigantic. Sergei is about 6'4, 6'5, and he towered over him. Sergei knocked him down in the first round at about 2:40 in the video, even with big amatuer gloves and headgear.
