Although its quite a good video overall, just a few things I would like to point out.
Cap route 1: I briefly thought you had failed when you began circling the base whilst being in the state of overdrive. Although it might cause confusion to some players, it wouldn't be too useful against good players. Your health was below 20% by the end of that route, and you were still close to the enemy base (not going much fast either).
Cap route 2: It was okay, although you could hit higher speeds at grabbing the flag with some RJ improvisation.
Cap route 3: I was expecting a front route at first, then I thought its going to be something different (in a really cool way), next thing you're doing is flying vertical whilst being in your enemy base vicinity. If you did that for the fun of it, cool. Don't use it as an actual route thou, it will end as a tragic kill- fail cap.
Cap route 4: A very nice route, I was expecting one of the more used caps. I like the way you improvised there. Good cap.
The last combo jump: You could use that to turn it into an e-grab, as the enemy gets away with your flag, do that multiple combo jump, grab their flag before they even know whats happening.
Cool music btw, Dubstep!
