Early on in my windsurfing life (aournd 1989 or so) I got the good advice to try really hard to get gear that was all the same, especially sails: always buy a quiver of same make and model. It makes everything much much easier in an already difficult sport. The Chinook masts are just soooooooooo much cheaper than the same thing from other brands, and it's the best quality.

You're gonna make me fire up a wind alert, aren't ya. : ) ...Right in the middle of a Cubs game.
