We'll if it's mainly rails and med jumps I would stay narrower. As soon as you go wide the skis will get heavier an the swing weight will increase. I would look at the infamous. That was May fav park ski last season. So light and easy to throw around, they are symetrical too so they carve switch really well. They are soft and buttery in the tips and tails but mid underfoot so still carve ok. Last seasons had some durability issues but those have been resolved now. Those would be my suggestion. Filthys would be worth a look too but they will be quite a bit heavier but still a fun ski.
