How do you guys regard the Hi-Opt I system? W and W/O Ace side count? Any opinions about the DHM systems and the Canfield Expert and Master Systems?

Do you guys have any contact info for Lance Humble (originator 0f Hi-Opt I and II systems), D. Howard Mitchell (originator 0f DHM system) or Richard Albert Canfield? I know that these names are pseudonyms and that Cnfield is a single name used by a group.
