I'm new at all of this so don't know the pens that you mentioned. But I find myself using my S.T. Dupont Orpheo rollerball (either platinum or silver, I think) and platinum Cross Townsend rollerball a great deal. Both are somewhat heavy. I also own a Grifos rollerball, also heavy. My Delta Napoleon Bonaparte rollerball is gorgeous but a little much for every day--which is why I usually default to the Dupont or Cross.
