Mike,
Once you get the mast "just right" for a lightweight team, it is too bendy for a heavy team. Once you get it stiff enough for for the big guys, it is too stiff for smaller, lighter weight, teams. There is no "just right mast" for all size teams. THAT IS THE PROBLEM! So, What is the solution? Different mast layups for different weight teams?
Where does it end? This question is really stickey!
