I'm trying to sell my roper as it doesn't fit either of my horses but on my gelding when I put it on it seems like it fits until I have him trot then it slides forward over his shoulders and causes back to tilt up I have tryed 1/2 in pad 1 in pad and no pad back cinch does nothing to help hears a couple pics I shot today first 2 before I trotted him 2nd 2 are after trotting saddle moved about 2inches forward. Any tips to help it fit better? Can't buy a new one till I sell this and haven't had any one show interest at all.
