RO/WO Hood Scoop post

What has everyone used for a center support post in their hood scoops? I have an R0/WO style scoop on my 67' Belvedere. Its fine except on single lane highways when a semi blows by me the other way it sure make that scoop flutter more then I like.

I have always made mine out of small aluminum tubing from McMaster Carr. They even offer polished aluminum.
