I understand your opinion and you're entitled to it but like I mentioned before I proven this statement over a thousand times with a thousand plus different shooters, so I will have to respectfully disagree with you.Tuning the bow and fixing the shooter sounds great in theory, but in moments of stress a shooter will fall back to their most basic level of training/ability. I can take just about any bow and get it to shoot bullet holes by torquing the grip just the right way, but when an elk is screaming in my face, I'm going to revert to the grip I've developed over time. A bow is not perfectly tuned until the actual shooter can consistently produce perfect arrow flight. If the shooter has bad form/mechanics, you'll be chasing your tail tuning anyways.
I would not trust anyone to tune my bow for me – that's not a slight against you or anyone else – I made it a priority to learn how to tune because bowhunting is about the only thing I care about in this life. Luckily I had great mentors who stressed this.
As for the OP's question, I don't do any tuning unless I'm there with the person (for reasons stated above), but I guess if I had to ship one out, I'd get it bareshaft tuned and grouping broadheads for me and hope for the best. In a perfect world the owner would just need to make a few tiny adjustments.
