      When I worked for Lancair, I did prop testing on the their ES with the ACI, MT & Hartzell.  I believe Tim Ong has those numbers.  The ACI was close to the MT and Hartzell in cruise, but clearly the worst of the 3 when it came to take-performance and climb.  The ACI seems better suited for the IV or Legacy.  The Hartzell was a knot or two faster in cruise.  The MT (new simitar blades) performed the best and is currently on their factory plane.

      I just purchased the Hartzell for my ES because I like the durability and overall performance.  The MT requires more maintenance.  Yes, the Hartzell is heavier.  My electrical systems, oxygen, AC, etc are mounted aft in the fuselage to accomodate the difference in weight.

      Hope this helps.
