I gravitate towards clothing that offer a lot of adjustability in the way of venting. And during a hike I'm going thru a self questioning of my comfort level and acting on it. Most the time the adjustments I make are done while moving... Not with every step mind you,but often enough to be ahead of sweating problems. My personal comfort threshold is if I feel the need to put on more clothing when stopped.- and take that off when on the move..
