Reply to MIDI Fighter and Ableton optimal latency settings?

The recent article on DJTT had me messing about in the midi preferences area of Ableton and I was wondering if there was a recommended setting (if any) for the MIDI Fighter?

In the preferences area of Ableton, when you select the little dropdown arrow next to your "USB Audio" driver for the MF, you have a few options that until now i had thought only pertained if "Sync" was on. Call me crazy but it appears that changing the mode from "Midi Clock" to "none" seems to have some sort of effect (more responsive?) and I wanted someone from DJTT to confirm whether or not it matters? I am using a Lenovo Thinkpad T400.

If there is a recommended setting in this area, other than to have "input track" and "input remote" turned on, I would love to hear the official word (and perhaps an explanation why?). Also is there is a suggestion for "MME" versus "Direct Music" when using the MIDI Fighter?
