Hello Bill.

A few days ago I was asking about this, to know if the rounded prop
spars has to be oriented in some particular grain orientation. Akihiro
Danjo said: "I think there will be NO difference, though I use A-grain."

So your test is in concordance with Akihiro thougts, because flexion
will be almost the same regardless the grain orientation.
