David; you also no doubt have the "high pitch" IVO blades with the "plus" on the hibs, right?  My FWF (Tommy James Glastar) came w/the low pitch blades so I will fly initially with them and then buy hi pitch or switch to Cato, etc.  Tommy said to to fly his he had to add pitch going down the runway to increase thrust as airspeed increased.  Ross Farnham w/ turbo Subie 6A has said similar things in the past as well...
Be safe out there and have fun w/it!
