MM cartridges


I recently picked up a used Merrill table and having an audiomods arm installed. I am interested in installing a MM cartridge only. My choices are Grado reference, Soundsmith Aida, or Decca London super gold. Has anyone tried these cartridges and can offer feedback?

Does the AT-150 MLX perform on symphonic music or is it for rockers only like every AT used to be ?
AT-150MLX all the way. But, don't count out Goldring, Ortofon, and Nagaoka.
Gentlemen: Thank you for all your responses. I will consider all the advice. 20 years ago I dumped all my analog gear. Actually gave away a Decca Garrott, Garrott P77, Signet TK7-SU, Signet TK-9E and a AKG P-100LE for free to a young audiophile who used Analog. The one I have is a Rega Exact which should mate well the the Audiomods arm. Always liked those AT carts. But the Decca Garrott was "the one".
