In a Mooney 1 cm of ice drops the speed from 150 kts to 142 kts.
In a Cirrus 1 cm ice drops the speed from 155 kts to 118 kts.
Both have laminar wings.
Also, these answers to my remarks aren't really answers, they are opinions of Cirrus lovers. I bet it's gonna be more than 25.000$ to fix the 10 year mandatory BRS replacement. How many people know this ? Why is Cirrus hiding this ?

PS: There is nothing more fun than a SE-ME discussion and why is a Cirrus a bad plane discussion.
