Replying to Time for a ski upgrade?

Hello everyone. I ski a very small resort in Ontario. I ride park 99% of the time and I was wondering if new skis would benefit me. I am 6ft tall 220lbs. I am currently skiing Völkl Bash 86’s. They are 172cm long but i think they have a pretty late rise tip and tail. I was wondering if upgrading to the 179cm K2 sights would we worth it? They seem to have a early rise tip and tail so would they feel the same? Is it worth it?
