boxes are great. I 100% agree that they should be phased out of/de-emphasized in competitions. But aside from that, all the talk of how "easy" they are, or stupid they are is dumb. They are a great way to learn, and build confidence. I had to learn rails on the nuttable, double barrel, early season rail at killington years ago. That was hard, intimidating, and I definitely took my lumps. I wish I had had a nice flat box to learn on, to get used to the whole concept before trying it out on rails.
For instance, I'd like to try 270 disasters this year, and I'd much rather learn it on a flat down box first. Sure, it's not the same, but I could probably learn to get my 270 rotation down a lot better knowing that if I over or underrotated I'm not totally fucked, because I'm landing on a box.
