Interesting.... there's a significant contingent of Lancair operators flying MT props, with IVP's getting 350kts and 360's getting well in excess of 200, 220 not unusual.  Sounds to me like there's another agenda here.  I imagine it might be possible to get higher top ends with a fixed pitch aluminum prop, but that prop is going to be optimized for that flight regime and that regime only.  Consequently you're going to see lower rates of climb and anemic performance during slower speed operations.  That's the main reason for the variable pitch prop, to get maximum available performance during all phases of operation.  To make a blanket statement that the MT underperforms some other prop doesn't tell the whole story, but I'm sure I'm preaching to the choir. FWIW.
