Klyne and Uesugi Bros....nice :)
Cart loading is very preamp dependant so if you have never used the Uesugi phono section it will involve several unknowns. (Best load, and if higher ratio sut into lower sensitivity input or lower into higher sensitivity input sounds best- and yes that affects load)
You could probably buy and try and sell a few sut based on vintage mic trafos ( ebay etc) without much $$ lost at the end and learn from the experience.
End of the day i use Silvercore often...
