Some of the elaborate features have to be executed perfectly.....to the Nth degree, to realize any benefit. OTOH, if you keep things simple and are capable of building straight, the returns on your time and efforts will most likely be better.
A good example in this particular case is the airfoil, it needs to be pretty accurate to get all the low drag benefits at speed. So we'll see how that goes, I'm chewing on ideas somewhere between regular fabrication/building techniques and CNC molds.
