I understood the comment by sydney to mean the complementary angle: 90 - 17 = 73 degrees because I measured mine, and got a rough 70 degrees with the stem insert itself flat on my desk and measuring along the axis of the stem extension as best I could (rough in any case). Was that correct? If so, then the Nittos are even flatter given your examples, aren't they? They actually look it from the pics you posted.
