Replying to Look DIN settings

I'm thinking about purchasing look pivot bindings, but I'm not sure if I should buy the P10's or the P12's. I'd like to buy the P10's because they are a lot cheaper but I'm not sure if the DIN will be high enough for me. Right now, I'm 5'10', 160lbs. I can't really find any specs on the bindings. I think my DIN on them would be somewhere around 6 but I'm not sure. I also don't want to jack the DIN up and weaken the spring. Any advice is apreciated.
