Some prop makers measure pitch on the rear face of the blade and some use the cord line of the blade airfoil. different prop makers may use different blade airfoils so this is another area for pitch measurement to differ for the same affective pitch.
Ed Sterba built me a couple of props over 30 years ago when I was flying a Sonerai and as good as he was then he can only be better now. Personally, I would consider asking anyone else for advice concerning a Sterba prop a waste of time. I don't mean any disrespect toward the posters here, but no one knows props on Sonerais' any better than Ed.
I would agree that the clipped metal prop is a wall hanger.
The change will have an affect on your weight and balance so adjust accordingly.
