I use the exact same setup I do for deer. Expandables, I didn't lower my draw since my bow has like 80% letoff and I can hold it for quite a while at 70 pounds I think I'm only holding like 14 so I can sit there all day with my bow drawn if I have too
Anyhow the combination seems to work
If you're allowed to in your state, I'd suggest using a blind like a double bull. They sure make it easy to do the hard part; getting to full draw on a bird without him seeing you
