DD and Dpony have come on brilliantly over the summer and DD is keen to take him hunting with Pony Club. Although he normally behaves very nicely XC etc. now I think we definitely need a stronger bit first time out just to be on the safe side.
DD normally rides him in a jointed metal wilkie with a cavesson noseband and running martingale. When Dpony has a mad 5 mins he chucks his head up to take off so I don't think a gag is the answer but rather something with a bit more poll action? An instructor has suggested a rubber pelham but DD's not happy about riding with 2 sets of reins and I'm not sure if putting roundings on so she's only got 1 set make it less effective? Dpony is still young and has a very soft mouth so I want to strike a balance between looking after him and giving DD the best chance to manage him. He doesn't open his mouth to evade the bit so don't think a grackle or flash is necessary.
Sorry-very long post but does anyone have any thoughts or suggestions?
