I have owned various vandenhul grasshoppers, Clearaudios, a Lyra Helicon and most recently a Lyra Titan. At least in my Rockport, the Titan has been a very nice match and a rather significant improvement over the Helicon and I would highly recommend it to you. One further thought, matching the cartridge to the tonearm is really important. If the mass and compliance of the cartridge is a mismatch for the mass of the tonearm or the tonearm does not do a good job of dissapating any energy sent by the cartridge into the arm, you will not be happy with the end result. Another way of saying this is that there are some combinations which are very synergistic, for instance the Colibri in a Rockport arm. I would focus on trying to identify what cartridges work optimally with your particular set up.
