Sorry for the slow response!

Temple flaps are very easy to maintain and they make life a lot easier for for concealing the sides. I couldn't do withouth them anymore to be honest, as my sides have gone back so far...

I should tape down my flaps, but a lot of the time I don't because they stay in place quite well. If I'm going into very windy environments, or into water, then it's good to have them taped down. It's also very easy to tape them down, and they stay down quite well and it helps the whole front to stay in place.
