sounds like you're built about the same as me. 916s, unless you're hitting legitimately scary big jumps where you're in a situation where you're better off with your ski staying on if you don't stomp something perfectly, are going to be way overkill. now that they brought back the steel toe, they're bomber, for sure, but like someone said previously, you don't want to be running your binding at the very low or high end of it's DIN range.
as an example, by the DIN chart, i should be running an 8.5 on my bindings, with a 315mm boot sole. i usually ride a 9 or 9.5 in the toe and 10 in the heel. this puts me dead center of the DIN range on my pivot 14s. even though they don't have the metal toe of the fks155/185 or pivot 18, they're still super burly, aside from the brakes. the brakes suck, sorry. that said, i think the pivot 14 is what you're looking for.
