I hope not...the Pure is one of the handful of Lat64s discs I really enjoy throwing. It probably has more to do with Trilogy pumping discs out left and right that the older molds get less attention versus the newest must-have hyped putter.
Here here. The Pure (primarily Opto) is a fantastic throwing putter that really was ahead of its time. The Fuse (OG Opto, none of this newfangled OptoX) and Pain (Roc3/ Wasp-esque) are also two older Lat 64 molds that fall into that category.
