You are right, but if you get a burning desire or a need to just do a specific ritual so then do it.
A few months ago or so, I asked on a different topic if I could do the communications RTR as I just really wanted to, brothers and sisters in Satan told me that I can, so I did it and I felt so much more better and happier after that RTR, that even things started getting better.
Communication with my parents for example, got better and with less fights, communication with my pets (family members) got better in that they started listening to me and coming to me often.
These are just examples of good things that came about after doing the RTR I trully desired to do.
But if you just want to stick with the FRTR+T, then so be it, nobody is shaming you, brother.
Take care!
HAIL SATAN!
