Personally i dislike the idea of movable aero, but would like more introduction of deformable aero like the old Ferarri rear wing and the rear wing of the RB3 at Barcelona.
If this idea could be put into practice on the front wing as well it would be a good idea i think, meaning that you had the stopping power, but also had the top speed advantage.
Thats my thoughts, maybes i could be sold on movable aero tho, but it just sounds unsafe to me.
