Here's my advice. Throw away all the bits you have and get a curb bit with swivel shanks and a snaffle type mouth. Make sure that you can put two fingers between the curb strap and his chin and make sure that the bit is contacting the corners of his mouth and maybe making one wrinkle in the skin. Or Ride him in a simple ring snaffle. He is not real soft in his face and mouth so you need to work at that. Put a small amount of pressure on the reins and as soon as he gives even a tiny bit give a release, but don't give the release or increase the pressure untill he gives his face. The reason he is mouthing the bit so much is because he is resisting it not because he is in pain. It's not about the bit with him it's about resistance and the horses inability to break at the poll. The softer you get him the less he will fight that bit. Just ride him and work on getting him soft in the face and otherwise trained and the mouthing the bit will take care of itself.
The grazing bit your horse is wearing in the first video is junk. It is the worst bit ever made and should be thrown in the garbage. It is designed to be cheap to build not to fit well in a horses mouth. It's also made out of aluminum which will dry out a horses mouth where copper or sweet iron will encourage salivation.
