Pin on hoods? yay or nay?

i have a Cf hood, just using the normal hood latch, and it seems ok, ive taken it to 90 without trouble but am a little afraid to take it further. maintly because the hod jumps up and down between 60-80, after 80 the hood is held up by the wind, and i really dont want to have my hood come off at 90+mph.
