Watching the Blade 20th anniversary stage show. I'm curious, are they using a different helmet style?
It looks like it's missing the clear layer over the face, and it's noticeably not yellowed.

Maybe they got out the ol' baking soda mix from the studio or made a new one?

I would hope they made a new one. However, since they wouldn't even fix the display suit's mask for so long, it has me doubting it.
Part of me is thinking maybe the "Action" suit, that needs roll around and such, might have gotten a new mask (Since Garren's mask was also missing the clear cover, too).

Granted, would be strange to put the money in to just updating the action suit, but Toei's decisions don't always make sense.

Maybe the personal initiative of theater actors?

So if you pay attention to the Blade and Barren helmets they only have half (I think the upper half but can't double check at the moment) of the clear panels also outside of the torse/shoulder pads the Ace form suits are all of noticeably lower quality compared to the ones used in the shows. As these suits are the ones that tend to be used for events so that if anything happens to them it wouldn't impact filming of the show.

Ironically the cheaper quality materials lead to them not aging as bad as the show suits.

I am now down to the final seven episodes of Kamen Rider W and I should be finished with my rewatch of the series, along with Goseiger, sometime this week. I am planning to do a rewatch of Kamen Rider OOO not long afterwards.

Just watched Kamen Rider ZO. It wasn't anything amazing, but did its job well in that it provided a complete Kamen Rider story within 45 minutes. It's worth checking out if that's what you're looking for, and I watched it because I was in the mood for Kamen Rider but didn't want to dive into a full series, but I wouldn't call it essential viewing by any means.

Not only I finished my rewatch of both Goseiger and Kamen Rider W, I have just started my rewatch of Kamen Rider OOO as of today. I have been looking forward to revisiting this series for quite a while.

Time to count the medals, 1, 2, and 3! :D

Man, I've been a fan for a little bit over 10 years and have yet to re-watch anything sentai or rider (aside from re-watching Shin Kamen Rider, since the first time I saw it was in theaters in Japan and didn't have subtitles)

I guess I'd just rather watch something I haven't seen yet.

I've been watching Amazon, Black Sun and some movies. Plus, now amateur voice-overs of riders in my native language have begun to appear, so I watch them as support.
