I constantly rotate calls, I have 2 boxes in my vest at all times, and i own a couple more so every hunt i make i rotate one box in and one box out. i do the same with my mouth calls which i have a plethera of. i only have 2 glass calls so they stay in the vest at all times, and 2 slates so they stay in at all times, but i still rotate use on the slates and glass to. 3 out of the last 4 birds ive killed was with a magnolia game calls glass call. i tend to use that call more than others, but i at least rotate strikers between hunts. overall through out my short life, at one time i only carried a lynch fool proof and 1 mouth call, that's all my father ever carried. most of my birds were called with a lynch.
