I am one of those callers who thinks that set up is many times more important than exact prey sound
Agree!
I've called in a handful of lions and haven't connected because my setup wasn't the best. My first calling session led to a huge lion coming in that just "appeared" at the base of a large jackpine.
I seen the 'lump' there at the base of the tree and because I was trying to be so still and not move a muscle; I didn't want to move and glass it because I didn't think it was anything.
So I sat there for 30-40 minutes in the failing light scanning the areas with my peripheral vision while being perfectly still..... but I kept pausing that that 'lump' and 2nd guessing myself.
The lump never moved in all that time, and that helped me talk myself out of moving enough to see it through a scope. When I finally called it quits that lump was still there, still hadn't moved, but when I stood up and started stretching my back out that lump also stood up, it was a huge lion and it just slunked off. I missed my opportunity

So like a military sniper, learn and memorize every lump, every shadow, every dark spot..... and if anything changes...put glass on it!
