I see yout point but in any cases I want to keep 1 stereo input for my main cardioid mic . The other input will be use for 1 iem mono, and maybe 2 if conditions are favorable . If not, I'm just thinking about making 1 iem mono + 1 audience mono with my second pair of mics, omni . Just to plug all the channels at every show .
My goal with all those cables I'm talking about is for sure not to buy a 2nd recorder . Not only a question of money, more a question of number of things to enter in the arenas .
