What Should I Rig a Tornado With?

I'm building the Tornado from the supplied plans, and I was wondering what good components to rig the boat with would be? I'm not really sure where to start on this, or what my constraints are, so any help would be greatly appreciated.

Cheers
Here is a site that would be an excellent source of tornado info.

I have a new aluminum Marstrom mast extrusion to start with and can ship. Where are you? Pete 909-800-5237
