Best cartridge for very old worn vinyl


Fellow vinyl junkies,
I have a weakness for old vinyl (particularly early oval Argo choral recordings circa 1958-1969).
Almost invariably these suffer from worn grooves, the effects of god knows what misaligned agricultural arms/cartridges over several decades, even the ones marked “near mint” by professional sellers.
I have a range of cartridges, including Decca London Reference, Koetsus, SPUs and Shure V15 111.
These go in an FR66 arm. Not all of these are necessarily ideal for this job...:)
What do you guys reckon is the best cartridge for these types of records?
Key requirements are not to be flustered by the challenges these ancient slabs of vinyl hold while doing the best job of producing something resembling music ?
Cheers !

It's not necessarily the cartridge itself, but the size and profile of the stylus.  Many early cartridges used spherical or elliptical stylii that rode fairly high in the groove.  That's where the wear will be.  If you can get a cartridge with a VERY SMALL line contact stylus and play records that have been recently cleaned, you will likely be contacting the vinyl surface deep into the groove.  That part of the record may have never been played before.  You will be hearing unplayed vinyl.  There might not be any pops or noise that deep in the groove.  
I've got vinyl that wasn't ruined by my old turntable cartridges...amazingly...I assume my Much Better current rig just gets at the grooves better in every way, and I clean my vinyl these days so there's that.
I have tons of early 1950s mono jazz and classical recordings. I've found that the AudioTechnica OC9 MK III gets to the bottom of the grooves of these mono recordings and gets some previously unplayed music out of them. Low surface noise too.

Howard, do you have any vintage MM, except for MI Decca ?  
Just curious 
@chakster,
hi yes I’ve got a Shure V15 111 with a new hyper elliptical stylus from JICO (not SAS type)...
It’s a surprisingly nice cartridge- I’ve yet to try it properly with the old vinyl
