Holy ****. Well i guess i got the answer to my question. I think i've heard of ballistik but never seen that glove, the rest of them i've never heard of being UK brands and i've spent a lot of time researching gear over the past few years. The impression i got was that heroic came out with the glove first as their design (something along the lines of todd designing the template and the factory making it), and then Jimmy getting his hands on the heroic template, making slight alterations and calling it his own. It appears that the factory must own the design for this glove (the most obvious similarities being the break in the back of the hand and the slider design) and allows companies to start with the base template and make their own changes, as yes all of those gloves clearly start from the same place, and just end up slightly different.
Thanks for clearing that up. I'll edit my first post so anyone who researches this in the future can skip ahead to this page.
