Replying to Line Afterbang 2015/16, bindings & mounting

So I'm doing a season this winter in Risoul and have always liked park skiing although I'm distinctly below average. I have some Blackcrow Viators 2015 which are an all mountian park ski but quite stiff so cover me for bigger air etc.

I've posted before for ski advice and for some soft jib/butter skis was reccomended line afterbangs. Is there much difference between the 2015 and 2016 apart from price and graphics?

Also have no idea about bindings, I've got marker free 10s on my crows which have never caused me any problems. Should they be centre mounted etc?
