I am in the Eagleks camp here.
I am nearing 50, with arthritis ever so swiftly starting to wrack my body. That and 29 years as a truck driver has left my body bent and bruised. I have had my L5 fused, and would be in no shape to ward off an attack, unless it were a single attacker,in similar shape such as I.
Now up the ante a bit, and throw in the fact that a probable attack will be from someone much younger, and possilbe multiple perps, and my days as a street grappler would be over very quickly.
I'm not saying you guys have a point about H2H, but one also must come to grips from a reality sense, and not give a false sense of hope to an individual who in the majority of attacks would be getting the short end of the stick really fast, by thinking this would serve them well.
