I ride my horse in a chunked snaffle straight bar, despite he is strong, doesn’t work well with sharp bits and doesn’t like cold bits either. I want to change his bit, do you have any advice ?

I would maybe try a jointed Pelham with a really loose curb on him. My horse is also sensitive and I’ve been trying get him more responsive to my voice as well so that I don’t have to use the Pelham as much any more.
Hope this helps!!
