Matt,

Welcome aboard! The weak spot you're talking about apears to be a benefit (although I doubt the designer planned it that way.) I've repaired the T_ _ _ T more times than I care to admit, but what I do is lay in some pieces of carbon fiber rod across the breaks and it really beefs up the fuse. (I just lay the rod in the corners and sprinkle on some baking soda and then smoothe with my finger....I then apply some thin CA and voila! Please, only do one at a time or you'll have a mess.)
It's sounds like some flyers are getting anxious out there! Spring is almost here?

Peace,
