Replying to Recommended Ski Height for Park

I'm 5'11, riding 171s (Armada AR6s). Height feels a little small and I'm looking for a softer, more buttery park ski for hitting rails/doing switch ups, but also want a ski that'll perform well on medium-large jumps and is light enough to do spins. My all-mtn skis are 185s (Nordica Soul Riders), which feel a bit long for park skis and heavy for spins. Was wondering what height I should aim to target and what skis (was thinking Faction Prodigys or Line Chronics).
