Don't go pontoons or ARGs if you want to use them all over the mountain except groomers. Don't get me wrong, they are sweet skis but not really that versitle. I use mine on big pow days, then Atuas on regular days, and first gen pistols for park. You kinda need 3 pairs of skis for either of those.
I would suggest 185 Scratch BCs, Fischer Atuas (186), 179/189 Seths (depending on your ability), 181 Mojo 105s, 181 Thugs (really fat, these are somewhat out of place), 186 prophet 100s, 181 Scott P4s, 185 ARVs, 183 Gotamas, 182 VCTs. You really have to think whether you want a stiff/medium/soft ski because there are so many types out there to decide from. ARVs are the softest, then the Seths. Atuas, Scratch BCs, prophets, P4s and VCTs are all medium-ish flex, then Thugs, Mojo 105s and Gotamas are stiffer. With the Goats being the stiffest of those.
Decide what flex you like, and whether it is important that you have a ski with a 100+ waist and it will narrow it down.
188 JP vs Juliens and 191 Ants you could throw in as well. The JP is soft and really straight. Great in pow and the park, but it isn't as versitile as the others mentioned. The ANTs are a big stiff ski, but can be versitile if you can power them. Personally I wouldn't go less than 95 in the waist or more than 105ish for what you are describing, but I would go over 100.
