If you really are a 10/10 on groomers (I assume that means you have some kind of racing background?) then you're probably not going to find a ski that performs as well on groomers as you would like and is still fun to take into the park or pow. But, seeing as you only ski groomers 20% of the time you probably aren't worried about it that much.
If you don't like charging there are plenty of skis that will do the trick, many of which have been mentioned already, like the pettitor, SFB, and blend, and also the moment PB&J, Armada TST, volkl bridge, and others.
If you are looking to charge, options become much slimmer, as there aren't many skis that are fun in the park that really charge, but the volkl mantra and blizzard bonafide, are both good skis. The Bonafide is especially good. Neither would be too much fun in the park, but will allow you to ski faster and harder all over the mountain than any of the others mentioned.
So, all depends on what you want to sacrifice, really
