I am an 80 percenter 
You are in great shape and I do believe you when you say that your legs are your strongest bodypart because they used to be ahead
of your upperbody in the past so why would it be any different now?
However I wonder what your plan looks like since you've said you are going to compete in September.
Will you try to keep this level of conditioning the whole time (which I assume since you've implied this in the first post) while adding some more muscle?
Or are you willing going to sacrifice at least a little bit of conditioning in order to gain more lean muscle? I think I remember that you eat very clean at times,
do you not get bored especially if you're doing this for like almost a year? What was your last competition?
I still have a hard time believing that the guy next to you is actually over 200lbs but it could be if he's not as lean as one might think he is.
I think there are actually quite a few similarities between our bodies... we both have weak arms, strong legs.. born to be rather small and lean than huge.
