I put a hack on my big guy and he woahs beautifully but lacks in the turning department. I put his tomthumb snaffel on and he rocks socks on turning but takes forever to stop or he will fight it and pull past the bit. Found a gag hack that has the basic dog bone snaffel (not a twisted dog bone snaffel) and the typical rawhide covered hack, my thought is if one works better for turning and one works better for stopping a gag hack should be the answer to my issues... right?
