it's not a sport, it's Korean martial art. Taekwondo WTF was created for sport issues, olimpics etc. but Takekwondo ITF is still a martial arts (its not just about kicking). Anyway you have to be really agile to be good in Taekwondo. Your tall, if I was you I would do some kickboxing, muay thai, boxing etc. If you want something more spiritual Wing Chun is a missed idea. It's nothing spiritual in it. I trained Ving Tsun which is similar, and it's not that great as they say. It also looks gay and doesn't fit anybody except Asians
To be honest spiritual martial arts are usually weak on the streets, they're being practiced just as a hobby unless you're talking about Muay thai, some styles of Karate and Taekwondo. Grappling is really nice when you're in semi-dangerous situation. It's better to perform a painful armlock than to kick somebody's ass.
It's better than Karate, Boxing and all stuff like that. Don't practice anything as it'll only confuse your kick ass natural talent
