I took mine off while in the middle of the bumper install that I could not finish all at once. So, I drove without it for a couple of weeks and hood would flutter bad enough that it would hit the stop with a clunk.
After intalling a stubby, it was better but would still dance around enough to make my wife squirm. It would also 'feel' like it was catching enough wind that it would slow down the Jeep.
I replaced the rubber hood straps with a pair of Daystar ones and that sucker is solid as a rock now.
