Hi Allen,
Hope you've found our Welcome Center. If you can do "the norm" on your current board and you can carve your downhill edge, you're probably ready for an alpine setup.
Yes, all-mountain carving boards like the Donek Axis, Prior 4x4, and Coiler All-Mountain are very capable carvers as well as in the powder and all-terrain. Although if you think you want to go right into a freecarve board, you can't go wrong with the Donek 171fcII. Incidentally, my best day in moguls was on one of those. It's 19.5cm wide at the waist, which is fairly wide, making it pretty maneuverable and floatable. And it carves like a dream.
IMO, hardboots are superior in moguls because of the extra support. I find it difficult in softboots to stay centered while riding moguls. I always feel like I'm about to go "over the handlebars" in softboots in moguls.
Good luck!
