Dressage Peeps - Bit advice

[moneypit1]

Fly schools well in a kimblewick (cambridge with the rein on the last slot for maximum poll pressure). He is jumped in a german hackamore but leans too much when schooling hence the kimblewick. He is not strong, has a soft mouth but likes this combination for some reason. He will only accept a straight bar. I need to replicate this bit with something dressage legal and being a dressage numpty know nothing! Was thinking of a straight bar fillet boucher (does that exist). HELP!
