This has to be the most underrated disc in discrafts lineup.  I love shallow putters and this feels perfect in the hand.  I putt with rubber blend glow ringer gts and drive/approach with z flex and esp.  these discs in premium plastic are dependably stable aren't too glidey and hold straight before ending with a nice smooth finish.  In more base plastics (xsoft, jawbreaker, rubber blend). These are perfect putting putters.  In rubber blend they beat in to a neutral disc and just sort of hold that seasoning.  The thumb track is great and their lack of glide really gives me confidence on long putts. 

I was so stoked on this disc, I bought 2, but honestly...nope! The "rubber" blend is like a DX plastic, damaged very easily. I don't know who wants a throwing putter that gets damaged easy...but yep too fast for a putting putter and even more, I took this out for a glow round and it sucks. The glow looks cool for a few seconds, but doesn't last.... and then the dang thing is black!

She flies nice as an over stable putter, but ya... definitely not going to make the bag. 
 

The Ringer GT is an extremely dependable overstable putter! The flight is most similar to a zone, but they are completely different discs. This a shallow, low profile putter with a slightly rounded underside on the rim. The groove top is more comparable to the feel of an Innova Rhyno than a Banger Gt or Buzzz Gt. This disc has a slow flight, and will fade every single time even into a headwind. The glide is extremely low making it easier to dial in your approach shots. I would not recommend using this disc as a putting putter except maybe in extremely windy conditions. This disc feels equally comfortable for forehand and backhand shots.

I bag both the Zone and Ringer Gt. Though similar, I feel like I can trust the Ringer GT to not skip and also not travel nearly as far.
