Replying to A few boot questions

Next year I'm buying instead of the usual rentals. I didn't have trouble choosing a ski and bindings but when it comes to boots I'm at a loss. I ride freestyle, I want medium flex. But I can't figure out if I should go narrow or wide. I was looking at FT Descendant 6, FT First Chair 6, and FT Drop Kick. If anyone can give me some input on these boots or others that might work please do. Also if anyone can help me with the narrow or wide thing.
