Replying to Salomon rocker2 100 2017 vs new ski?

Salomon rocker2 100 2017s are my current skis and the suit me perfectly for all mountain but seem a little stiffer and heavier than id like in the park, this may just be me being used to lighter skis, but i have been looking at playful buttery skis for future such as line blends or the 2019 on3p magnus90. I mainly hit jibs (can bs and fs 270 off and others so am still fairly new) and love playing around on rollers and on piste on the way to and from jibs. Should i just get good? Or would a dedicated, playful park ski be a good idea? Any (affordable!!!) ski recommendation or advice would be much appreciated.
