i had a pair of 12 bindings a few seasons back and one ended up exploding, literally on the take of of a jump, wasn't a fun experience. turns out they just were not strong enough construction for thrashing in the park, so i moved up to sth 16s. on a side note, they had been pre-releasing a lot, but showed no outward signs of wear. when i took the un-exploded one off my ski, inside it was all cracked and about to do the same.
Not quite what you're looking at i understand, but a 10din binding is not going to be as reliable and durable as the 12s. sell them on that point mostly, and the safety issue.
