May I ask another questions, for education on BP/W.
This wing is for single tank. It will have to have the STA, because it doesn't have the slots. Am I right?

This wing doesn't need STA, because the cam bands can go through the slots and tight into the back plate, STA is optional. Also, this wing is for double tanks. Am I correct?

The 360 (first wing) is better than the horse shoe one because it is a full cycle. Am I correct?
Thanks in advance.
