Replying to Will longer skis feel better

I know this is borderline gear talk but I thought I'd get more replies on here so.

I'm going on a trip and I got a free day of rentals last time I was there so I'm gonna use it this time. My skis are 166 and im 5'10 135 (I know they're small)
I ski 60% trees, moguls, pow, etc. And 40% park and groomers. I'm gonna use them for the first three days and then rent on the fourth day (the rentals are 2014 Blizzard Regulators in 179. Do you guys think these are gonna feel better? I've skied small skis all my life. I'll ski mostly park on the last day with the big skis. Does anyone have any experience with the Regulators?
