Reloft DB foil to match NACA 0010?

Hi,
Actually related to my previous post. Compared my foil to the NACA 0010. Very close except for the trailing edge. Performance wise is it better to use the NACA 0010 for the foil or just knife edge(not a true knife edge, still a .050” flat trailing edge)the existing foil? Composite laminate is not included. (Chord is 12inches & thickness is aprroximately 1.1 inches)
Red = NACA 0010
Green= current foil
Orange= knife edge configuration
Thanks in advance.

 

I would be inclined to simply square off the trailing edge, leaving two sharp edges. The flow is going to separate from your steeply chamfered edges, so they may not be that much better than the rounded trailing edge.
