I personally WOULDNT send it without his acknowledgement...if it were to get lost in the mail or something, you would think he just blew you off. Ive read that he was pretty backed up as of recently, keep in mind that he's just a regular guy pumping these out as fast as he can while attempting to keep the quality at a top notch level...its gotta be overwhelming at times. I know it must suck not having your Chuck perform correctly while you wait for an answer from him...but, personally, I would wait for a response. Just my opinion...you know what they say about opinions!
