Like all of us here I aim to be a well rounded man who know how and when to fight. As such I have spent a significant portion of my life learning skills that aid in this aspect of being. But the last few decades I have failed to maintaining my hand to hand skill set. I trained in Taekwondo as a kid, wrestled, and played football. But as I entered into adulthood life happened and I pursued intellectual and business endeavors and let some of my martial training atrophy. Thus I am trying to rectify this as I enter into my 40s. I have found a local dojo and started Tang Soo Do instruction but I feel that it needs to supplemented with some form of grappling. I know of local gyms that train in both BJJ and Judo. Any thoughts on which would compliment Tang Soo Do better?
Most BJJ gyms will have the sparring (rolling) done on the ground and don't emphasize throws. I would suggest this route as it probably allows for longevity of training due to less chance of injury (since you're not being thrown on the ground). As with all things, it depends on your goals, but that's my two cents given what you've written above.
