Weighted vest - 12 box jumps, 6 Snatch Balance, 6 L Pullups Workout

I did this WOD on a wim, with VERY little warm up time.
I was wearing a 20lb weightee vest for the entire WOD, except for the Post WOD where I did a modified version jumping higher, doing OHS, and C2B pullups for cariety and explosion even when tired.
I did 5 complete rounds with an additional warm up round with regular pullups
I then did an additional round with NO vest, doing higher jumps, OHS x 10 and then Chest To Bar pullups
This was a fun WOD and I tweeked my back a bit doing the box jumps.. I was bending over a little bit and then exploding upward. I was really trying to rebound right off the ground. I progressed each round with higher box jumps. I started with 95 lbs, but then used 100 for the other rounds.
