I have all the Kaiyodo parts to make essentially the same as Matrix's, though I'm using the same gloves Hurricane uses, plus the HUrricane helmet.
It's interesting to see Matrix's comp pics. I love the HT helmet but the Kaiyodo still does look a little better, though the SSC DX dome looks a tiny bit too small on the Kaiyodo whereas the HT facemask/dome proportions look spot-on.
Because the Hurricane is the Kaiyodo facemask but with quite a few subtle mods that increase the accuracy, I think it's probably the ultimate though I wish the Kaiyodo had a better option than the trimmed SSC DX dome (Hasbro looks too big on the Kaiyodo.) Maybe I'll cast my HT Vader dome and see how it looks.
HT is still far and away the best Vader out of the box. With my PC points I'm hoping to get it for $250 shipped.
