[quote=jaybird1111]Yes, there are differences. It comes down to different ways of depowering the rig.
If you have a 'bendy' mast, you over rotate the mast in order to induce camber on the minor axis, and also creates drag/turbulence in the forward part of the sail.
Stiffer masts use prebend tuning, which combines with extra downhaul purchase and bends the mast on the major axis, with less drag.
The sails are cut different for each approach
IIRC, wither White or Fragale discuss the different modes in their books.
I can state from personal experience that older NACRA Squares had bendy masts with little, perpendicular spreaders and the upgrade was to either install swept spreaders or get the stiffer mast which usually had swept spreaders installed.
