Sure, I don't mind an overhaul every 4 or 5 years. I just prefer that in those blocks of time there's a semblance of continuity.
And, while unrealistic, I think that when there's a complete redesign, that should be announced early, maybe even with preliminary sketches. I know members who marched a corps in a year there were uniform changes, and they were majorly disappointed. I guess with the more frequent changes it becomes less of an issue, but the uniform is part of a corps' image, and part of why people want to march in a specific place. Of course they grin and bear it, but if you grow up idolizing Maroon and Gold, then show up and get handed an all black uniform, it's certainly a bummer
