I’ve had problems from the beginning with the fit of the G2. Beautiful displays, optics, and sound, but it rides my forehead, squeezes my temples, etc. It’s been love/hate.
Another virtual pilot mentioned the Studioform Creative G2 strap and counterweight kit. It totally transforms the fit. No more forehead or temple/eye pressure, the headset actually fits proper now with the stock face interface. You can get just the counterweight or top strap, but I really recommend both.
They have kits for other headsets too.
