Jworth, the Charisma V2 should work perfectly. It is a little stiffer at 17u/mN but it is also three grams heavier than the blue point. So it all cancels out. It has Clearaudio's best stylus in it. I have never heard one but it should be killer. The Maestro is excellent so you would have to assume the Charisma is even better. According to Clearaudio's spec the Charisma will track at 90 uM which is fabulous. Very few cartridges can track that well.
If you get it do let us know how you like it!
