Ok, I created a couple missing categories. Please post links and suggestions regarding those category pages, I'll update them, I left this thread alone for long enough for someone else to take this up if they wanted something else.
Now, would it be possible to hide 'child categories' from the main spgear.org page?
This way, it would be possible to have a more structured classification.
-Rock Protection (would be the only thing showing on spgear.org)
--Active Pro (hidden on spgear.org)
--Passive Pro (hidden)
When you select a Parent Category, it automatically shows the child category's Gear without having to attach them.
