Can't add anything else to this.
I was in the almost-exact situation as you salomon-skier, I'm about 6'0 and 200 pounds and skiing with S912Ti at DIN 10 last year with some pre-releases, specially on landings that was. My shop guys was telling me I should just get 12's because according to the DIN chart I need to be on 8,5. I was able to convince him of the fact I need/want a 914 but then got a good (read: fantastic 35% off-) deal on the STH16 elsewhere so went with the STH16.
I mean, I ski at DIN 10, soon going to 11, the STH16 starts at 9, so there's no problem is there? Specially not if you can get it almost at the same price as a 914... ha
