I like neck cranks, not only do I see them as a useful weapon but I find that training and defending against them really helps me strengthen my neck, just like any other sub if you dont train it your more likely to get caught with it.
But I've got to agree with Balto that not doing leglocks would be way worse and coming from a background of Sambo i just don't understand how other arts ignore them to such an extent.
My neck is pretty fucked, so you can pretty much tap me by touching my neck with your pinky finger.
Like someone said, one of the main problem with them is that the pain often doesn't kick in until the next morning.
I remember one time I was being too much of a dick to tap to someone putting me in a guillitine neckcrank when I was in mount... I eventually escaped but afterwords I realised how much I was gambling with.. and how fuckin bad my neck felt.
Neckcranks are destructors and should be banned
Two guys (including me) has gotten injuries from neckcranks.
I got totally destroyed and got a prolaps in my neck (c6)
This was in April, and I still cannot run or train anything
