No long neck for me...I'm actually a pretty stocky build, so I have a strong neck, and can stay IN the hold for a while, but I usually start getting lightheaded from them choking my esophagus moreso than the artery. I can muscle out of it sometimes, or sometimes just ride it out until they get too tired. But not always...it has a LOT more to do with my inexperience at the ground game and how to escape it or just putting myself into it too easily than with my complete inability to defend against it.

Basically, when it comes to all things grappling, I'd what you call a "nub". I'm pretty good at the stand up aspect and apparently have some great KO power, but I just don't have the experience with grappling/subs to do any better than "just ok" on the ground.
