what characteristics of a shaft will influence the MPF Ratings in regards to the S- Slice/H-Hook/M-None
We look at the torsional stiffness, tip stiffness and overall bend profile. Stiffer overall, especially in the tip section(which includes a lower torsional stiffness), would most likely yield the H rating and the more flexible overall (which would include a higher overall torque rating) would most likely yield the S rating.
