Best tonearm for London Reference Cartridge

Hi,
i have a Decca London Reference Cartridge (LRC), actually mounted in an older Mission Mechanic tonearm and would like to ask you with which tonearm one can get the most out of this wonderful cartridge.
The player is a Kuzma Stabi Reference and a Thorens TD 124, other arms i use are Sumiko MDC 800, Shindo Meursault and old Decca for ffss cartridges, but in these i haven´t tried it yet, but all these tonearm run with other cartridges so fantastic, that i don´t want to change them.
Some people recommend the long VPI 12.5, 12.6 or 12.7 tonearms. Have you some other suggestions?
Thanks very much!
