Thanks for looking at the Severne Blade 06 sails, for your possible new set of sails.
They wont disappoint you.
We have been looking at your info regarding sizes, your weight, boards and conditions you sail in.
The 5 sails will cover most conditions with your 2 boards.(good choice)
The sails will work with both SDM and RDM masts. For the mast you already have, we have heard good feedback from other riders, that the North Viper 430 and Fiberspar 400 will work OK for the sails.
Let us know if you have any other question, or need more specific info.
