Prestige jump saddle help!!

[jump jet]

I am hoping somebody has an answer for me. Does anybody know what Prestige saddle would best suit a flat backed warmblood? He has almost no wither and fitting a saddle to him is a night mare! I've had my heart set on a prestige and was just hoping that one of the models would fit him.
TIA x

I have a relatively flat backed Connie and my saddle fitter said the old Merediths may fit him.
