I use Knap Tactics, but I always turn Play for Set Pieces on as corners are so OP with the correct rotuines, but I'm not sure if that's secretly detrimental or not.

I personally like the training schedules with recovery the most, I try to keep my backup players sharpness as high as possible and recovery seems to preserve sharpness better than rest. Also I notice that for some reason the Attacking session yields an unusual number of injuries, more so than Defending or Overall. I could be wrong, but it's something I've noticed in my saves.
