No worries, your stuff is pretty great!
Yeah, I highly encourage using sends to bus effects for things like verb and delay. Your system looks pretty monstrous, so I don't think it'll help you that much in regards to CPU overhead, but it can definitely help your soundstage sound tighter. I usually make three "verb" buses, a very big one, a tight room, and a vocal plate. I put the word "verb" in quotes because for some, the vox plate in particular, I usually use a delay instead of a verb. Plus it makes it easier to dial a mix in, since there's just one effect to set and the rest is just adjusting your send levels.
I hear you about the "new" stuff. I just finished mixing our record and I have to a crap ton of housecleaning before I can start working on new material.
