Can you explain what you mean by syphon? If you were to say that to me, I'd immediately think it's the same as a vacuum press. So, if it's different, I'm intrigued. Sounds good. I don't think the Rockets require that, either. Regarding the PID, that's exactly what I thought, as well. I think I might use it for the first week or two, and then never think about it. I've seen some PIDs now include an automatic shot timer, which I could see being useful.
