Remember the drag starts with your worst foot, looking at your left foot their (assuming your goofy) as angle looks less than the right, the left foot toe overhang is pretty large. Also doesn't need to be pow, but also soft spring snow has the same effect, which I'm not sure how long you get on the east coast? but before I knew enough and moved to wide boards about 12 years ago, I had terrible toe grab in spring slush, which made for a crappy time riding.
Certainly the comments above are correct, in that you won't feel any problems without some fairly serious lean on groomers, but I just wanted to point out the above scenarios where foot overhang does come into play, it does get annoying.
Personally now I have been on wide boards for over 12 years, I don't find any disadvantage at all,if anything I prefer the stability, theres never been an occasion where I needed faster edge to edge.
I guess what I'm saying is, I think you should consider the negatives of both scenarios, basing the decision on your own previous experience. ie. If its narrower than you're used to, with more toe overhang, with the amount your showing, I think there will be days where it will come into play vs HDX where you will not have an issue. But if you have never had a wide board and you like making smaller snake turns, then you will find it a little mellower in turn transition.
