I hit the callaway razor fit stock aldila trinty shaft,stiff today.There was no stock matrix 7m3 black tie shaft in the store.My swing speed or head speed was averaging between 100-105 mph,thefore I was told to use the stiff shaft.On the Calliway web site it says the matrix 7m3 is for the better players with faster head speeds.Do you think a swing speed of 100-105mps would benifit from the stock matrix shaft over the aldila trinty or our there lots of other factors i need to consider and should wait to hit that shaft before making dicissions,
Thanks
