I think your on the right tack nem, causebest way is leave it smaller then go out at spinner at spinner length and shape. if i have a fan with a 2 inch long spinner, i make the divergance that size right at the fan, even if i only have 80 percent FSA. cause really as long as its spinner shaped, its no more turbulant to the air than the spinner itself right? and the air wont care or see it cause its goung right around the spinner anyway and wants to go out a bit at this point anyway, it only will see the diameter its traveling in. its worse to have it too big cause air will get in there and go almost all the way back and will have nowhere to go, except to churn and cause drag till fan decides to process it.
