KM is what I originally had my eye on. The place that I have the year's gift certificate doesn't offer it. I think any one of the martial arts will be good for me.
That's awesome you have a years gift certificate. Can't beat that! You'll enjoy TKD. I can still remember my first belt test. We had to do a number of things but one thing was a running, jumping, kicking a board and breaking it. I was so amped up that I jumped way too high and ended up totally missing the board. Not one of my finer moments.
My son is wanting to take something and I've been going back and forth on what to put him in. He has a friend that already takes BJJ and the kid is a beast. Basically when all of the kids are messing around they all fight like crazy to get him from taking them down. Once he gets them down you know one of them is going to be begging him to stop.
