True, I just kind of naturally hone in on mma because that's what I do (well and I'm a competitive grappler). In any case, just because a particular combat sport bans certain techniques, doesn't mean you won't be able to deal with them in a fight because, at least in mma anyway, most of the banned techniques are similar to allowed techniques and the defenses used for those would work on the banned techniques, I think I mentioned a few instances in fact. That's not the case with everything you might find on the street but much of it, and for the stuff that can't be handled that way it's not really that tough to sometimes throw in some time spent on that in training if you care about self defense. True though, it does depend a lot on the sport format you follow. I train for competition in a few different organizations with differing rules so I train in a wife range of techniques including those banned in some organizations. In some ways there is carryover, for instance heel hooks are banned unless you are a pro, yet training consistently on the straight ankle lock will make your heel hook better because it's a very similar technique so making the jump from the straight ankle lock to the heel hook isn't difficult. All this being said, I tend not to worry too much about the fact that certain things that can be done in the street I don't train for because I know how to avoid physical confrontations, that's a big part of my philosophy on self defense.
