I teach a combination of Aikido & JuJitsu. Have studied various forms of traditional Aikido (Tomiki & Ueshiba), and WJJF & BJJA JuJitsu, as well as BJJ. I think some of the arguements here are valid, but are glossing over a major factor - time. Any art takes time to master. BJJ & the like are instant gratification arts, the rewards are fairly immediate. Aikido takes a lot longer to gain a realistic profficiency in, leading some to question its validaty. When "felt", Aikido DOES work in reality (it was my core arsenal when doing "door" work) and it most certainly does encompass effective ground and restraint work. H
