I'm in the same boat as you, I'm mainly a stand up guy (it's where I prefer to be in the ring and definitley on the street). I know enough ground work to defend myself and submit some people in the ring and most on the street. I don't plan on making a living in the UFC, so I'm pretty happy with that. I'm not into the pink hair, skull and flame t-shirts, and camo painted face thing either. I can definitley say one thing, I have noticed that my years of kung fu (stances, tension training, floorwork, etc.) have given me a foundation that a lot of these mma guys can't disrupt. I still believe in kung fu.
