Any advice, experiences of this system from others? Practiced this for years. It's always interesting to get feedback from different perspectives. Training does involve resisting partners and the hi-gear training is good as long as your partner just doesn't give way to you intentionally. I find the outside90 principle mostly available to use when an opponent is engaging in a consistent linear/forward motion. As the main principle consists of the splayed fingers, forearm across the neck. However, I do understand that (to my understanding, correct me if you feel differently) it teaches you to get back to a point of being able to get on the aggression and back under control of a fight or person if necessary - where this "spear is a bridge to your next move" comes in. SPEAR seems to be more of a natural tool to be aware of in close quarters where you might have absolutely nothing else even though you do have a strong martial arts background - going by Blauer's word. However, I feel as though I don't have as much confidence as I should have with this system. I feel like its not so much of a primarily used method where you find yourself in any altercation and just go to outside90 straight away. I feel like I'd need to have experience using it in a confrontation outside for me to see it go to work as drilled and practiced.
