The Logic is the beadless compliment to the Link. This disc has a smooth, comfortable rim and a good height. It's not too deep, not too shallow, just right. The Logic excells in the circle, but can also be used for all of the other putter needs you may have.
 
The EXO Soft plastic is a grippy and tacky plastic made especially for close ranged shots. Its similar to Latitude 64's Zero Medium/Soft plastics.
