How deep is your grunt call setting?

I have used Primos hunting calls ever since ive started hunting. Each grunt call has a number of settings; (YB) young buck, (MB) mature buck, (TB) trophy buck. Ive always wondered what other people set theirs at I am worried that i might spook a buck/deer if i use a mature buck setting, but i want to ATTRACT a mature buck….what do you guys set it at?

I’ve got mine set deep and don’t call agressive right away. After they have had a few encounters I don’t want to turn them away, I just want to bring them in. If im ratteling it depends on how long I’ve ratteled, I try agressive and softer when ratteling.

I think it depends on the size of deer that you want to call in,If it is a small one I wouldnt use a deep call, However if you listen to deer grunt it dont realy seem to me that you can jude his size by his grunt. Ihave heard small bucks that would scare ya to death, and big ones that you could barely hear.
