get the griffons. such a solid binding and will be sick with your obsetheds. ive got em on my fujas and they are perfect.
and i have no clue why people are saying the griffons are heavy. maybe compared to the px12 they may be a little heavy, but i cant see how a few ounces can make a huge difference. the swing weight feels the same with my fujas and griffons as it did with my publics and shitty marker bindings that weighed nothing, and my publics were 10 cm shorter...
and every binding contains plastic. yea it would be more durable with a titanium toepiece or what have you, but the griffon is still a very solid binding,
