I just got the new Duotone f-type 6.8. On Duotone website, it says that it rigs best on 430 / alt 460, best RDM / alt SDM. On the sail bag, it says 430 RMD only. I tried to rig it on NS Gold 430 SDM as this is what I have, but it wasn't possible so I had to buy the NS Gold 430 RDM. With this mast it rigs very niecely but the cambers are pain in the ass. I hope I will get better at setting them, because the first time it took me a lot of time and it's very easy to snap your finger (which I did).

I will let you know more once I try in on the water.
