The modern London cartridges made by John Wright have much better quality control than the original Decca Special Products output (which was indeed a bit of a lottery).
I have had Decca for 40 years now, and they will track most records. No they won't do the cannons on the Telarc 1812 Overture, but very few cartridges will track that.
Traditionally they were best mated to damped unipivots. The lack of vertical compliance meant that the vertical vector energy could be dissipated in the unipivot without affecting the cartridge performance. I've used my Maroon, Garrott Bros Gold and FFSS MkIV C4E (John Wright rebuilt with fine line tip) in my Hadcock 228 and Schroeder tonearms (Model 2 carbon and Reference) with great results.
