Not necessarily the best, but some I love, and I advise newer fans to check them all out... some amazing scraps and a few upsets

Just K-1 and It's Showtime, i.e. no elbows style thai-boxing... Muay Thai is a whole different beast, I'll leave that for another day.

*Anything from K-1 MAX is amazing, but I had to single those five out as favourites that I still watch every now and again

*Anything with prime JLB, prime Leko, Manhoef, Hari, Hunt etc is generally destined to be a quality, exciting HW fight
