If you had a Benz cartridge would you let someone

Else retip it. From my understanding with the distributor Benz is about 12 to 18 months behind on retipping. Would you let someone in the United States retip it for you. The dealer and the distributor both say it won't sound the same If Benz doesn't retip it. But who wants to wait all that time for a retip. Who in the states has retipped you're Benz cartridge that you have been happy with?
