Orphan equipment like grousers and radio

Some equipment has specialist roles (bino,camo, gld) but a few pieces seem to have almost no applications eg radio and grousers.

I do use grousers on the 122tm as some data suggested it was better than turbo and the reload is so long a rammer is of questionable value.

Are there any other tanks where the ground resistance is so bad AND mobility is important that grousers beats turbo?

And does anyone use radio? I love the idea and played with it on the ebr 90 and elc, but other equipment always seems to benefit them so much more, that you can’t justify it.

I used to use toolbox when it was free to love and on Casemate TDs where the quick track repair was nice, but now improved hardening gives you this and so much more, I can’t think of any niche for it.

And spall liner seems like a pure noob trap outside of meme ramming builds.

Any thoughts?
