I will reserve my opinion until I see a new Tornado Carbon mast in action.

I have been playing with a shortened Marstrom's A-Class carbon mast with a cut down Tornado sail for a couple months so what I have learned may be of some use.

The mast is light and stiff. It's about the same weight as a Laser mast

It is partially foam core. The foam area and the carbon thickness seems to vary along the length.

The mast is stiff but more flexible above the hounds.

You set the mast curve with diamond wire tension. I can set mine to match the luff curve in a Tornado sail. I have heard some scary numbers like 900-1200 lbs from some A-catter's. I am using ~300-500 pounds.

For the first couple of weeks, steel wire stretches a lot compared to the amount of adjustment. For a Tornado, I might go with rod.

The Diamond wire tension is controlled by one bolt at the base of the mast. It's kind of wild to set everything up on a windless day and then make the hollow spot in the sail appear and disappear by playing with one bolt. We are not talking about a lot of adjustment, 2 turns or less. As I write this, I'm thinking "Maybe I should mark the bolthead to see if it's backing off".

Compared to a tapered Tornado mast, the carbon mast is a lot less automatic. It's not going to flex and adjust the sail shape for you. The mast will hold the shape you set and expects you to adjust the shape as needed. It's like an extreme version of the pre-bent Tornado rig.

On my setup, over sheeting has turned out to be a no-no. Sheet in hard on a puff and I slow down.

Now, if they would just fit a captive ball base to the Marstrom Tornado. (I can use Marstrom's base, I just don't like having an adventure every time the mast goes up or down.)
