I found also that the Brooks B17 is more comfortable (to me) when the height is a bit lower (~5mm) than the recommended height based on my leg length. One of my legs is slightly shorter, which sounds a lot like your saddle dimple asymmetry observation.
So it might be worth simply lowering the B17 first to see if that helps. (If mine is too high, I feel it in the hip joint of the shorter leg.) Some people deliberately offset the saddle from center alignment for this reason, but I have never tried.
