I use both for my JMW 10 arm wands. The VPI jig will allow you to quickly and easily set overhang and overall cartridge geometry.
The MintLP protractor will allow you to align the geometry to the cantelever, as opposed to the cartridge body with the VPI jig. It's a very useful tool and well worth the cost, IMHO.
