for me Masato vs Souwer III will always be the fight that ended the best era of kickboxing, an epic fight not only for his historic meaning
Andy Hug vs Hoost II
Sittichai vs Grigorian (all the fights in Glory)
Noiri vs Kaito
Noiri vs Superbon(already a classic for me)
Kyshenko vs Souwer I, II and III
Kiria vs Ristie
Petrosyan vs Souwer I(I still think that this was the most impressive Petrosyan win, more than his second win in the K-1 tournament)
Petpanomrung vs Trindade II(Petch finally became the undisputed greatest kickboxer alive)
