I remember seeing the Cabs that year and wondered, "What were they thinking?" I believe (though not at all certain) it was a decision driven by prevailing judges' opinions about streamlining the look of the uniform, and 'updating' the corps' image. Apparently, it just didn't have the intended effect or results. Sanity and good sense returned the following year, as Elphaba indicated.
In the case of this latest move by the Hurricanes, I am reminded of the 1965 season when the Bucs switched to shakos. As I recall, it was even a front-page story in the old Drum Corps News. The new headgear made for a good-looking image overall, but eventually they returned to the aussies as part of subsequent uniform changes, returning to their earlier image. I can't help but wonder if the same thing may happen eventually with the Hurcs. I can't say I dislike it, but it does make them look like some other corps now, not the Hurcs I remember competing against. But then, like so many corps, their uniform has changed several times in the intervening the years anyway.
The Hurricanes "Gestapo/State Trooper/Motor Cycle" headgear are actually an "Iconic" part of senior drum corps.
Going WAY BACK to the late 1950's/early 1960's I can vividly recall the corps marching in the Barnum, swagering down Main Street in those olde black uniforms and later their first "Satins" topped with the trademark "Gestapo" hats. . Wow. Great memory.
Best of luck with the new headgear.
