To make the ride smoother, you've got to make some decisions.
Each one of the basic steps in the recording process is necessary. Without one or another, a recording isn't going to happen.
From pulling cable, to patching, to sound check, to gain staging and tweaking, it all has to be done. Get air into the room. Cool it down for a bit before the session starts. Hit the AC again during breaks.
If it's not the temperature that's the real problem, and you REALLY REALLY don't wanna do something, then don't. Get rid of the things you don't wanna do, and use the money from that to upgrade the gear you do wanna use. Then get better at doing whatever that is.
You may see it as a loss, and it more than likely will be. Just chalk that loss up to the game and keep on moving forward.
