Would a continental dutch gag be a good bit for my horse?

a dutch gag will only make this problem worse, horses throw their head up to relieve pain or pressure, maybe not even from the bit, check the noseband and head peice is not too tight on her poll, go and get a loosering snaffle, maybe even with a losenge in the middle to stop knutcracker action, she may just have a really sensitive mouth, i had a horse with this problem. she was sold to me in a pelhem and used to throw and shake her head, i put her in a snaffle and she was fine.
