The El Grande is a great large pen. Total weight is dependent upon the material used - Truestone, M3 and some woods like cocobolo or Osage orange will give you a fairly hefty pen. Biggest gripe I have with the El Grande is the visible plastic at the end and center.
The Atrax is smaller in diameter, but the more I use my Atrax the more I like it, even for someone like myself with my big paws. All the visible parts of the Atrax are metal, which I like.
An Emperor can make a large, heavy impressive pen.
Aaron at Lau Lau Penkits carries a rollerball that I believe is called the Havana, which is a large and impressive pen.
