im not an expert ,, but i usually just run a compact double sram gxp , i have a fsa crank in a hollowtech 2 BB. i assume your going from a triple oval ( interesting ) to a compact double ?
maybe your front mech is damaged or took a hit if its making noises it should not ??
maybe you could just try an ultegra crank or 105 ???
if you are doing gravel , i think it would be wise to focus on the crank more than the rings because then you can just get a bunch a rings to match your terrain and you will never be miss-geared on your rides , assuming you look at the route or do minor research into the terrain , elevation and such ...
