Seasons greetings to all.Thank you Jtimothya,but i was thinking along the lines of a "Best tractor" from Yip or
similar.
The UNI DIN geometry is a distinguishing feature of the SMARTractor only. There are no other protractors providing this tangential curve. If you want your cartridge aligned this way, you have to use the SMARTractor.
