Leveling weirdness

So I couldn't use the screw 2x6s to the sides of the joists like I did before since they are too tall by about 1/4" with all the cross lumber, which means its time to pull out all that stuff

 
I decided after consulting my civil engineer friend that pulling out all the 2x4s and 1" thick stuff and then running the 2x6s over it with OSB blocks screwed onto the sides would be best.  It's a lot more work than just screwing 2x6s to the sides, but at least doesn't cost more since I had a ton of scrap OSB pieces that aren't really large enough to use for the floor.

In the hammering that I did with installing those, I made a mess downstairs in the kitchen doorway...
