Vent Rear of the Hood

If you happened to see my other thread, “Taking it to the Track”, you’ll know that I went Tuesday.
I didn’t get enough runs to try the hood vented and held down. I ran it vented. Through the traps, I could see under the hood, and I could see that the front of the hood was lifting in the center! I’m going to add another hood pin in the center of the front. Yikes!
I do want to try it tied down at some point, to see if it helps letting the rest of it float.
