Replying to ON3P jeronimo setup?

I was thinking of getting a pair of this years jmos but I'm not sure what size ski I should get or what bindings to put on them. I'm 17, 5'9" and weigh 170, ski mainly park when I'm at my home mountain but when I go to other places I usually ski all mountain with a little park thrown in. I was thinking ski size to be 181 but I currently ski on a 174, the jmos also come in 176 Bindings I was thinking either marker squires or griffons, but what about jesters? Are they good for park? And what's the deal with schizo? Never really understood what they're for. +k for help
