4.6 Font sizes above 2 are not allowed.
I wold say it depends on the type of clientele you wanted. If you are looking for people that pays a premium, then it is not the place for you. Otherwise, change headline. I have run the same ad with different headline and no body change. The difference is incredible. Just keep trying different wording and track your result.
