2000+ mile test of different masts and a discussion on how the physical attributes effect the performance of my ride. It's all done on AFS foils but if you are contemplating a mast purchase and are interested in how stiffness, length, chord, thickness, and weight might impact your experience check it out:

That's a really great writeup. I just got the AFS UHM 80 and am looking forward to getting it on the water.
I'm currently on a Duotone DLAB 90, so it's going to be a lot shorter and stiffer.
