I own the Nasotec tweezers - gets the job done. Less chance of damaging the clips/cable with my chubby fingers. I've owned the Feickert protractor, but prefer the Acoustical Systems SmarTractor. Its pricey (~650), but worth it IMO.
what are your cartridge set up go to
What alignment tool are you using and has anyone used those forceps style tools that grip the connectors instead of basically squishing it ?
