Biggest problem we had was he had to make it like Da Vinci drew it. They compromised on the thickness of the bow, Da Vinci showed it be 6" thick I think I made it about 2 5/8" thick. The next show we did they wouldn't let me compromise, I had the bow figued to be about 2" tapering to 1" and they said I had to make it like 8" thick, I said ok. The bow would not even flex with #12,000 pulling on it. I got a laugh out of that one.
