Best Troika retip ?

Am about to acquire a Troika in very good condition with a fair bit of life left in it. Once it is time to redo it, who does the best musical job ? I had a Karma retipped by Benz and it was very mediocre. On the old forum there was, I seem to recall, a fair bit of discussion on this that I don't remember.

I have heard good things about Expert Stylus, the Linn rebuilds and Van Den Hul. Any others, or anyone who has been able to compare ?

Cheers,

Bob
