Overrotating aerials is always a bad idea. Doing so on a slider down frontflip is not just like a “normal” head-low deployment, since you still have some rotation momentum that works against the direction the canopy pulls you. So the openings feel harder and offheadings, linetwists, and other fun stuff is more likely to happen.
If you overrotate too far you can end up with a bridle/leg entanglement, or get your feet into the lines of the deploying canopy. So don’t wear shoes with hooks when doing stuff like this. Even if you already know what you are doing and you got your pull timing dialed in, a PC hesitation can put you in a really bad situation. But thats going to be a different post.
