They are definitely heavier than my TT30's and MalaVita's. How much heavier I'm not too sure, not too sure if it's going to matter either. I put them on a Westmark, which I believe is on the lighter side, so I expect it to balance out. I think I read over on the Angry Snowboarder that the ankle straps and possibly even the toe straps are Burton throwbacks. The ankle straps and rachets are very similar to those on my 2010 MalaVita's, that's part of the reason why I'm pumped on them. I weigh 185 without my gear on, that combined with the continous rocker on the Westmark should allow me to engage the hinged discs, at least that's what I was thinking when I bought them.
