Replying to What to buy

I'm relatively new to park skiing, and I have finally earned enough money to buy myself some skis. The problem is I don't know what to buy. The NFX look great, but they are asym, and I've heard that sym skis are noticibly better for rotations. Is there any real difference between asym and sym? The AR7's look nice, but they are also asym and pretty ugly. The 15/16 Da'nollies are incredibly tempting, but I can't find anything saying whether or not they are good. I ski mostly piste and waiste width id of no concern to me but over 83 mm is nice. I'm fairly certain the rossignol fks 140s are the bindings for me. The boots are whatever the fitter reccomends. Im 5 foot 3 inches and weigh 115. Im looking mostly for skis that will help me to progress from small to large features and help me learn rails. Anything under $450 is nice. Sorry for the typos. Im typing this on my phone.

Thanks
