I'm an experienced martial artist (20yr+ karate) who's recently taken up BJJ. I first saw Choke on VHS format a few years ago, and was mesmerised by Rickson's skills and attitude. This guy was (and still is) a real warrior.
There are a lot of MMA/UFC/Vale Tudo products out there now, but - for me - this gives a unique insight into Rickson's psychology and performance. The thing that sets him apart from his brothers (for me) is his strength and striking, which obviously are coupled with amazing technical skills. He hits with real venom, and his striking is a major threat that sets up decisive and relentless finishes, usually by rear naked choke. The quality of the opposition is obviously below what's around today in terms of well rounded fighters that train to grapple and strike, but the Japanese Shoot & Jiu Jitsu fighters are good (though I was annoyed to see Yamamoto hanging on to the rope to avoid being taken down & dragged to the centre of the ring, and him ALMOST getting a guillotine on)
I'd love to see Rickson (in his prime) competing today...think he'd still dominate. I've also watched Renzo's 'Legacy' DVD, which is fantastic too...but Rickson's conditioning is far superior and his striking a lot more decisive. Excellent product if you're a BJJ or MMA fan, strongly recommend it.
