Most of the masts might look the same, but often produced by different manufactures with different machinery, materials, climates, and technology, even if the curve or Imcs numbers might be the same, the performance outcome once down hauled in a sail, will be different. Being the backbone of your windsurfing sail, it makes a very important accessory for the rig. The same as having a suit tailor made. A large 9m slalom sails have different qualities and performance characteristics from a 5m slalom sail which is used in strong wind. The curve and stiffness of the mast needs to be developed accordingly. Most of the masts on the market are constant curve, but this is only a general term to explain the characteristics. What is important is the curve percentages values of the bottom and top sections of the mast, including materials, shapes, and reflex. These are values which are very different in each sail brand, and often kept secret. Therefore, the best efficiency is reached by having an integrated rig.
