Have a try with this surface using NORMAL-LIGHTER-CUSTOM
after each choice turn on control points:you'll see different densities and "topology"
supposing you want to move some surface's points,you can choose option that give less control points (easier to select and manage)
you also can see little curvature difference between LIGHTER and CUSTOM...choose option that fits better your target
Network try to build a shape following curves you draw,often make a compromise, giving unwanted bulges
I noticed choosing CUSTOM you force Network to follow your curves with a tight tolerance avoiding to go beyond them
This is fundamental when later you'll join the patch with fuselage and wing
Sorry for my English and for this explanation,maybe is not 100% correct
Let Michael,if not too busy, talk about different Network choices
