I see what you mean Scrap. I don't think my instinct served me very well when I felt that pressure and force. I got angry and forgot my movement and defence - unless you count having him in a head lock at one stage - and letting him go again because i was POed and wanted to hit him! Bad brawling s**t!

Thing that gets me is the less experienced guys on the vids in this thread might occasionally put a moderately hard punch in - especially if I walk into it - but I'd still call it light compared to sparring with the Nigerian dude.

I wouldn't feel at risk of getting concussed at all sparring any of the other guys because it's not consistant or deliberate - just enough to keep me honest. i don't feel pushed to use any force back because I know they're not using all their force with me but against the Nigerian dude i got to the point before we'd finished where I really wanted to kill him!
