Define what you are calling a freecarve board. What resorts do you ride?
If you mean something like a Donek FC or Coiler FC, you will find a board a little wider in the nose and tail with a tighter SCR. Flex will be slightly softer than a race board. Typically the FC boards have little to no taper. I tend to like this type of board when carving steep terrain. The board requires less input to get it on edge and carves a tight turn, so controlling you speed is easy.
If you mean something like a Coiler AM, Prior 4WD or Donek Axxess, they are wider than a FC, similar SCR, typically a little softer flex than a FC and have some taper.
The allmountain carving boards are extremely versatile, more so than a FC. They have a larger surface area so if/when you get into soft stuff, they will float better.
I rode a Silberpfeil for a few years. It was too soft for my weight. Last year at SES I rode a Donek FCI and absolutely loved it and am considering adding one to my quiver; that said, no way will I ever consider getting rid of my Coiler AM. It is my first Coiler and I am sold on Bruce's build, quality, flex, design... I liked my Prior 4WD, but it is a very different beast than the AM.
With either a freecarve or allmountain carving board, I think you will find that you do not have to be as focused and intense in your riding. You can step things back a notch and enjoy the scenery a little more while still riding a great performing board.
I have found having a FC or AM board is a great addition to the quiver when riding in Colorado! :D
