Privilege 482 Catamaran

[LiamONeill]

I have a Privilege 482 Catamaran. Last year I lost the mast in the Med. I have just received a new mast from France and was wondering what type of standing rigging I should have the rigger fit. I know there are different types of SS wire. Which should I use?
How can I ensure that the rig is propertly tuned as I believe the last rigger left the shrouds too slack resulting in my dismasting in a heavy beam sea.
Thank you
