Cartridge for SAEC WE-308 SX / Thorens TD 124 mkII

Well, I believe someone can have the arm of his choise and is perfectly normal to match the proper cartridge afterwards.
Even if this is against the common practice, (like trying to match the proper speakers while you allready have your favorite power amp) IT IS acceptable !
I think the influence of the cartridge in our system is of major importance, (comparable only with speaker's).
But given the facts like :
Convenience of adjustments, compatibility with the given turntable & even the whole philosophy behind the tonearm design (unipivot, knife edge, cardanic, dual pivot, sliding rods, magnetic, thread, air, ball bearings, 9"-9.5"-10"-10.5"-11"-12" , carbon, wood, aluminium, steel, titanium arm tubes, e.t.c) and above all the level of build quality and the joy of use, we can not acuse anyone if it makes his choice before purchasing the cartridge.
In fact I'm doing exactly the same these days :
I decide to keep only the items that I admire as masterpieces in terms of design, execution & quality control but also keeping a high std of performance per $$$
So, (after puting aside the legendary & extremely overpriced exotics) -by this point of view- my champions are the Thorens TD 124mkII and the SAEC WE-308 SX/ULS-3X above their contemporary ambitious competitors.
Believe me I've tried too many of them for over 30 years and I'm not going to abandon my reference point, I just feel this vintage vibe this period, with no regrets about the useful past and I'm wondering about the possibility of matching a modern hi-tech cartridge to keep my reference level, BUT without loosing the strengths of each part !
Of course now I'm facing the challenge for matching the proper cartridge that can fulfill the success of the package in keeping intact & even highlight it's character.
Maybe its difficult but not impossible to achieve this goal.
So, please any advice about matching their specific needs would be of great help, especially given the fact that no one can borrow cartridges for audition.
Its true that my precedent analogue source was way different :
Symphonic Line RG6 / Pluto 9A / Colibri XPP
While my all time favorite cart is the Goldfinger ! (unfortunatelly I don't have it any more)
Lately I've been trying the Reed 3Q with the Goldfinger on my TD124mkII but although the quality was of highest level, somehow I feel like I'm abusing the spirit and the integrity of this new for me logic about avoiding the hideously expensive stuff, so, I've get rid of the Reed also !
But do you really think that I'm downsizing right now ?
Do I have to accept this new path as a compromise ?
Is there any chance for my new-old front-end to reach an equally high level ?
Please feel free to express your anger about my choices or whatever can direct me to the right path.
Is the SAEC WE-308 SX with the ULS-3X headshell a worthy arm ? (I'm going to receive it next week).
What is the ultimate cartridge for this arm ? (providing a good match with the Thorens TD 124mkII also).
Any thought would be of great help.
Thank you in advance.
