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!

It seems not so many people have experience with the Deccas or Moving Iron cartridges.

There have been some changes: The mass of the needle mounting system was minimized by half. The bearing which carries the diamond is shaped in an L-form and does transfer the signal into electrical energy with just 1 mm of the transport way.
There are many indicators from the design aspect why this should be one of the best cartridges at all. Nevertheless the production quality improved too which used to be a small problem in the past. The differences between the Deccas are not that much anymore.

It is easy to detect that this cartridge is one of the most natural sounding transponders ever built. It displays the tone and sound like it was recorded – maybe a problem for digital ears.
Untill now i use the London Reference in my Well Tempered Signature (predecessor and more costly version of the Reference) tonearm, and this is a nice match.
Any other recommendations?
I've read on VA a good match with the SAEC WE-308 SX when mated with the heavy 18 gr ULS-3X headshell.
I've just bought this arm and I'm ready to give a chance to Decca Reference. I use the TD 124 II also !
I must admit that I have high expectations for this set-up.
My worst nightmare is a wrong cartridge/arm that could change the overall character & spirit of the Thorens.
ie : Steve (user510) reports bad about Ortofon Jubilee / Graham 2.2 and this is that I wish to avoid (a modern aspect of the usual hi-fi trends that betrays the rare quality of this TT while this arm/cart combo, performs really great in every contemporary Belt-Drive TT !!!)
We must stand with respect & integrity behind our TD 124 !
