As you can tell from my forum name, the Eindecker is one of my favorite aircraft. Your build is awesome, especially after being away for fifty years. Your return to the hobby and the presence of Wingnut Wings in the market place is fortuitous. Great kits to get back into modeling. I agree that Wingnut Wings' rigging diagrams are sometimes not as precise as we would like, but thanks to the internet and their reference photographs, we can usually determine what goes where. Understanding the rigging on the eindeckers is no picnic but it looks like you got it right.
Whatever you choose for your next kit, please keep posting your progress.
