Best Sativa for Martial arts

So, here's the deal: Indica and sativa are terms for varying differences in plant structures, not cannabinoids. Indica and sativa plants produce the same cannabinoids and they do exactly the same things. CBG, for example, is exactly the same from an indica as it is from a sativa. What your question is about is nothin but a marketing scheme. There's no way to tell how much sativa is in a hybrid. Numbers like 70% sativa / 30% indica mean absolutely nothing. This is because every cultivar is a poly-hybrid these days. If you want more cerebral effects instead of couch lock, you need to harvest when most of the trichomes on calyxes are cloudy. You don't want to wait until they are amber. Amber trichomes equal couch lock.
