Mint Tractor

I'm sorry, I apologize, please forgive me for doubting all of you who have told me of the need for the Mint Protractor. I got it today, and just did a quick check to find that the cartridge is indeed off set up with the VPI protractor that comes with the Supercout/10.5i. I read the directions and it is a very tedious, and slow going procedure, so I'll get back in a while and tell you if I hear any differences.
