Judge thrower here. Got to take my Fossil Fuel Wizards out to the course yesterday and play around with them a bit...
My immediate impressions when they first came in the mail were that A) these FF Wizards are VERY stiff, and B) they definitely feel like a Judge in the hand. Low shoulder and what felt like a more shallow inner rim than your standard Wizard... if you closed your eyes and someone put a Judge in one hand and a FF Wiz in the other, I think most would have a hard time telling which was which. Very comfortable.
After throwing the FF Wizard, I can definitely say that this is an awesome driving putter. Much more glide and a bit faster than I remember standard Wizards flying, likely from the lower shoulder/profile. I could rip on it and it would glide out straight and always finish with a reliable fade (this I do remember being a Wizard-y trait). It took and held hyzer and anny lines beautifully and I felt like I had a lot more control over the flight of the disc compared to my Judges. Putting was also very comfortable. After adjusting for the slightly more aggressive fade to the basket, they were dropping in just as consistently as my Judges.
My biggest quibble with these discs however is how stiff the Fossil Fuel plastic is. As I mentioned earlier, these discs are very stiff, offering very little give in the flightplate and virtually zero give throughout the disc itself. On a feel level, they don't compare with any of my Judges (Classic or Blend) and after a couple of basket hits, there were a couple of big chunks that had chipped away from the nose of the disc. Disappointing.
For now, this is the closest disc to challenge my Judges and I'll definitely be bagging the FF Wizard for consistent driving and upshot duties. If I could get these in a softer blend (SS) with the same mold and flight consistency, I would truly have my perfect putter.
