Wing stays

[DRCorsa]

Hello again. I will start making the wing stays but i think there are some problems on the drawings of the books. First of all, i can't see where WS6 is needed. Then, in the book, only one tube is bent while i have seen from people here that both tubes usually are being bended.
Also, WS5 is very short and without any bend, while WS4 is longer with a bend to go under the wing.
I have searched on the emmendments section but found nothing related to the wing stays. Any help will be appreciated. Thanks!

edit: OK, i found out why WS6 is separate and why WS5 is short. WS6 should be welded on WS5.
But should i bent both tubes or not?
