You ask why everyone think a C/S prop is NECESSARY. Short answer is, Everyone doesn't. Many people do like it, and to their credit, it is a great item, but it is not necessary.
As others have said, that's the beauty of the Experimental world. If you want it great, if you don't, then that's great too.
The C/S prop has advantages. It has disadvantages. Your choice.
There have been many, many RVs flying for over 40 years with F/P props and they perform wonderfully.
