Can anyone advise on what reins they use on their Pelhams please? I currently have a pair of leather continental type ones with sure grip (with the rubber threaded through) on the snaffle rein and another pair of thinner (guessing European) plain leather ones on the curb which I don't like that much. Would like to find a thinner width suregrip type for the curb as they seem very light and flexible - or does anyone recommend the half grip ones?
