To be honest, I didn't look at the link until after I posted the rodeo reply. I stopped doing HPR and EX not long after the BATFE started coming down hard. I had grown bored with it anyway, especially having to travel hundreds of miles and stay in hotels for a field with a decent waiver. Since paper or balsa cones have done the job in my LPR endeavours, I haven't used body tube material for a shroud in well over a decade. I'd pretty much forgot about it. The old "use it or lose it" applies.
