@Draftmare It really depends on why your horse likes the Micklem. Mine likes it because it primarily avoids the facial nerves and, to a lesser extent, because it doesnât press the cheeks into the teeth (determined through multiple bridle configuration experiments). However, today I discovered that the crownpiece is/was still uncomfortable for her - an even more anatomical crown piece on the PS of Sweden High Jump bridle offers the same benefits as the Micklem in the nose area plus more room for the ears. First the first time ever, she didnât rub her ears like crazy after I took the bridle off. Happy day! 
That said, the leather on the Micklem competition bridles is quite nice (although not quite as nice as the PS of Sweden, in my opinion) so if that bridle works for your horse and you are not trying to solve any particular problem, then your new purchase should be just the ticket!
