If a 54 tt is too big for you then I think definitely the 56. Although the top tube on that is a bit longer. According to the charge geo, a medium plug is 545 tt, and a 56 track champ is 558. If you put a 100mm (or shorter) stem on it that'd shorten the reach by 7mm and might make it a bit more comfy.
