I have been wanting to try a HS d-ring on my young mare for a while now and at her most recent dental appt. he suggested I try one as well. There seems to be a few out there these days and just wondering which one you have had the most luck with? Horse has low palate, fleshy mouth, sensitive....hates single joints and snaffles! I have only used the KK in the past but now there is the WH Ultra, KK Ultra, and the Dynamic Ultra.
I have had a loose ring KK ultra and a D ring WH for my similar sounding TB mare - low palate and picky about bits, so we need a thin bit to not gag her! She HATED the WH - the roller in the middle was too thick in her mouth and she just hated it with a passion. I debated getting the KK ultra D, but I ended up with the RS Dynamic D-ring which is basically the KK Ultra with curved ends on the mouthpiece and only 14mm thick - she LOVES it! The only thing is that it's not quite a big hunter D-ring, it's like a cross between an eggbutt and a d, but the mare LOVES it. She is better in the regular KK ultra than the WH, but the Dynamic is by far her favorite bit.
