"If" there is a possibility of a method of repair using known quality supplies, you "might' want to consider it,idk.
I'm definitely not a cable expert,I've only ordered & replaced a few over the years,but even buying from respected suppliers specializing in MGs, there's always been issues with quality or fitment.
I've purchased throttle cables for one of my Tontis from a well known US supplier;the cable & casing was of a low quality, slightly smaller and I had to do a mcgyver shim job to make it work,because the inner cable was too long.
Recently I purchased a throttle cable from Germany for my V11;same deal, cable and casing were inferior quality,slightly smaller and the inner cable was so long,even with creative shimming and adjustment,,, I couldn't make it work. I ended up mcgyering my old oem cable instead.
All that to say,buyer beware when it comes to cables.
If there is a quality repair work around that you do using oem pieces with known quality parts/supplies, that "may" be an option to consider.
fwiw fyi
