First of all please dont use caps, its the internets version of shouting.
Secondly both bolts are made of derlin so there is no diffrence there, so its just down to the hammer some people belive you should use a heavier hammer becuase of the lighter bolt, i dont agree with that and dont belive that you will see any significant performance gain.
I know a lot of people say that the brass hammer has a tendency to flake due to the softer material. so SS may be the way to go or you could get an titanium one from planet.
