It's a sad time, but FYI OSAGE ROOST will be pulling the plug at the end of the month. It's been a great 15 years since the start, but it's hardly ever used now and time to move on!
I'd be willing to try an all ivory call but it would have to be sold before I made it. My operation is too small to make something like that hoping to sell it later. That being said it would probably take me all day to make it, very slow and gently.
