Bits are about sensitivity and the snaffle is the mildest bit out there they say to train him with this one and then move to a twisted wire bit right before you work him then switch back to the snaffle and run barrels or whatever it is his job is. If you think the horse has an unexceptionably hard mouth I then was told they go to gags or hacks. Use that bit on the horse and then swap back to the bit he originality used to ride with AFTER he is trained to do so in the gag or hack they said to use a gag or hack that still gives a little that way it has the feel of the snaffle.
i forgot to add some important things:
They also said that a horse will need time getting used to the new bit before he will do well in it. To try a bit out for a week or two before giving up.
