I don't think Gas would be a good CHF, as he goes to ground a bit, and his passing (kicks) are far from good.
But he can take a mark, and his kicking is generally accurate, if not that long, and he gets under it a bit.
Therefore, thinking inside the goal square, Gas should go to FF.
His up and under kicks won't be a problem if he kicks accurately, through the goals. And when he falls over constantly, as long as he's playing in front of his opponent, he'll now get the free for push in the back.
