I know no way of testing such moves except performing them extremely lightly or stopping just before hitting. I don't always know it will work, but some of the techniques have been taught to me by high level black belts, Sensei Gary Khoury, and Sensei Vinny Christianno, others I have just figured out on my own. Trick moves usually bore me, I am not going to waste my time with something really flashy, especially if it doesn't work. When I spar, I usually distract someone with my hands and then blast a kick in with some hand techniques, or vice versa, sometimes I can just get a kick in anyways, I pretty much taught myself how to spar by emulating others who are better than me and taking their techniques that I like and worked on me. Obviously I use some moves from sparring drills that are taught, but they aren't my favorite "tools in my toolbox" to quote one of my senseis. I like how I spar, except for me hitting so light. I want to learn everything, but no one can learn everything so I make do with where I am at the moment.
To Jorvik, there are only a few kickers at the dojo I attend (I am one of them), and I have trained against them, and they all have different speed and targeting areas, one of them is a head shorter than me and can kick me in the head when in boxing range. I've got well above average skills for my rank from what I have seen in both kicking and boxing, most brown belts have neither and have bad stances and or flinch really badly, thankfully my stance and guard is good and I don't flinch anymore when sparring (I broke that habit a loooooooooong time ago).
To Bill Glasheen, getting into a fight around here on the streets would mean I'd need my knives, potentially a gun, because most of the people out on the street to fight are armed, stoned out of their minds, and don't give a rat's tail end about going to jail, so I'm going to stay away from that option unless I have to. If I get someone in the balls and their head is down in front of me they get to say hello to my hammerstrike, and anyone at the dojo I train at can attest to my crazyness and power when I hit with those. (there goes my hubris running away again) If I knew who the Rich Castanet person is, I'd talk to him, because Marine martial arts look awesome. I've worked with my cousin who is attending Ranger School in a few months, and he has been taught a few techniques and he showed them to me and they are nasty, and fun to practice.
Once again, thank you all for the advice, I'm appreciating it and already working it in to my training
