For dives that dictate more than one deco gas, once on the helium I stay on it. For a back gas of 18/45, I would switch to 32/20, then to 70% to smooth out the transition off the helium. Everyones profile and planning uses a different strategy unless you are diving as a team. If diving as a team then a unified plan is a no brainer.
