Anybody flying a 320/360 with Hartzell's blended airfoil prop?  I noticed they sell one for the RV series that is 72" in diameter.  I am looking for a good prop option over the 68" paddle blades.  I'd like to know how these Blended Airfoils are performing on our airframes.
I cant seem to get a straight answer out of anyone regarding good Hartzell prop choices for the Lancair 360.  Well, actually I did get one straight answer from Lancair and that was all they recommend was the 68"

Thanks
Bryan
