Replying to Salomon STH 16 a bindning that works in the park?

As the title says. Ive got a good price for this bindning and i wounder if this is a good bindning to use in the park? I ride like 90% park. I dont know how many pounds i weigh because I live in sweden and weigh about 85 KILO if anyone knows how much that is? Cause the sth 16 DIN starts allready at DIN 9  but that isnt much isnt it? because i will be skiing in the park. so the din would be like over 10 after all anyway?
GOD my english sucks bigtime. And I've even got a mom who is english speaking. god im ashamed over myself. peaceeeeeee
