I had the impression that the Sachs/Maillard FW was more a Sachs design than a Maillard because of the different cog tooth profile and tip shape compared to earlier Maillard FWs. The finish quality of the FWs also vastly improved when Maillard partnered with Sachs. 8 think the newer FWs also shifter better, so you cannot go wrong with the Sachs or Sachs/Maillard FWs they definitely are an improvement over the old Maillard design.
